My father was the son of Walter, the son of Alice, the daughter of Leah, the daughter of Rosalie, the daughter of Abraham, the son of Gitel, the daughter of Isaac, the son of Jacob, the son of Meir the son of Shmuel, the son of Yehoshua, the son of Rabbi Pinchas Halevy Horowitz, for whom this synagogue is named and grandson of Aharon Meshulam Horowitz it’s founder: my eleventh great grandfather.

So in a strange sort of way, I feel this Rosh Hashanah that I am coming home.

This family link got me to thinking about the roots and connections, and about the nature of Jewish history which in bible is framed within the structure of ‘toledot’ – generations. Judaism has traditionally passed on its defining ideas and ways of being within the family home and within the extended family we call community. The teaching goes from one generation to the next, the identity formed by watching and doing as much as by any formal learning.

( That said, from earliest times the idea of Judaism being a family tradition alone doesn’t really have traction. Abraham and Sarah famously “made souls” in Haran before leaving on God’s instructions ‘Lech Lecha’ – go, leave your ancestral land and go to the land I will show you” (Genesis 12:5). These souls are understood to be people they had converted to their faith; in other words, birth is only one doorway into Judaism, and the formation of Jews happens in a wider context than family alone.)

So I was thinking about the genealogical line between me and Pinchas Halevy Horowitz, the 13 generations between us, eight of whom were rabbinic families whose history I know only sketchily, and I wondered about what this relationship might mean, how his life fed ultimately into mine. I wondered too about how Judaism had developed in the almost 400 years since his death, what had changed, what had endured. For the truth about Judaism and about families is that they are not monolithic, they do not stay the same and their natural state is of flux and of change.

So if my ur-ancestor Pinchas was sitting here today in the synagogue that bears his name, what would be familiar to him? What would be radically changed? And what would be the golden thread, the Shalshelet haKabbalah, that ties his community to us, the latest in the toledot line?

There is a famous story in the Talmud (Menachot 29b) “Rabbi Yehudah said, “Rav said, “When Moses ascended to the heavens, he found the Holy One, sitting and attaching crowns to the letters. He said to God “Sovereign of the Universe! What are you doing? God said to him, “There is one man who will exist after many generations, and Akiva the son of Yosef is his name, he will in the future expound on every crown and crown piles and piles of laws.” Moses said “Sovereign of the Universe! Show him to me.” He said to him, “Turn around.” He went and sat behind the students in Rabbi Akiva’s Beit Midrash, and he did not know what they were talking [about]. He became upset but when he heard the students ask “Our teacher, from where do you learn this?” And heard Akiva answer “It is a law [that was taught] to Moses at Sinai” he calmed down.”

This very early Talmudic story sets the rabbinic principle that Judaism evolves, and that what was understood or necessary in one generation was not written in stone. Just as Moses would not understand the teachings of Akiva, so would Pinchas Halevy Horowitz not recognise much of the Judaism of the 21^st century.  Yet there is a great deal he would recognise. The great themes of this service have remained the same since the Rosh Hashanah liturgy was instituted and the mussaf service in particular is explicit about the leitmotifs of the festival – Malchuyot, Zichronot and Shofarot – the Coronation of God, the time for both we and God to Remember each other, and the blowing of the Shofar. Essentially, the service we have today stays true to the ancient themes of Rosh Hashanah.

Rosh Hashanah has a number of different names: it is Yom Teruah, the day of blowing of the shofar; Yom haZikaron, the day for remembrance; Yom haDin, the day for judgement; and less well known it is also Yom haKesseh, the day of concealment. The first three are clear to us, we hear the shofar calling us to attention, and speak of standing before God (and also in our own eyes) in order to judge ourselves. We think back over our lives and our actions in order to be able to put things right where possible. But what is the concealment of which our liturgy speaks when we recite “Tiku ba’chodesh shofar, ba’kesseh l’yom chageinu. Ki chok l’yisrael hu, Mishpat lelohei Yaakov. (Psalm 81:4-5) Sound the shofar at the new moon, at the [Kesseh] concealed time for our feast day. For this is a statute for Israel, an ordinance of the God of Jacob.”

It would make sense in the poetic structure for Kesseh to be the parallel of Chodesh and mean the new moon, and so the psalmist would be speaking of blowing the shofar when the moon is so new it could barely be seen, Rosh Hashanah is the only festival to be celebrated at the beginning of a month rather than at the full moon or later. But Kesseh is an unusual word to use and so it draws our attention. And suddenly the work of this season becomes clearer, though ironically the clarity we gain shows that the work of the Yamim Noraim is to both make transparent and then to obscure some of our past behaviour.

The core meaning of the word Kesseh is to cover or to conceal; the meaning of Kapparah is also to cover over, to hide or even obliterate. We are in the season of concealment – but who is doing the hiding, what is being concealed, where does it go and to what purpose?

One of my favourite teachings of how Jews do teshuvah, the work of this penitential period is that we do not expect to wash clean all our past actions as if they never existed, and start again as if we were newly born souls. Instead we have time to reflect on our past, to face all the things we did that we wish we had not, and all the things we did not do that we wish we had done, and to own up to them, to accept our own actions. We admit to ourselves under the watchful gaze of God, and we repent – an active behaviour in Jewish law that requires us to try to make good the damage we have done, to ask for forgiveness from those we have hurt, to resolve to change how we will act in the future when faced with the choices again. And then, when we have done all we can to repair our past, we are able to let go of it – not to deny it or to disown it, but to cover it (kapparah) to conceal from view (Kesseh) all the things of which we are ashamed and of which we have repented. We know that if we do this, God too will forgive us, the page will turn on our heavenly record so that a clean sheet shows going forward, although the previous pages of the book remains written, just hidden from view and not holding us back in hopelessness. We are shaped by our past but our future is not distorted because of it.

Reading recently about transitional justice I came across an interview with Vaclav Havel and was struck by the similarities in his views. Speaking of dealing with the political past and its effects, he said “It is important to find the right balance, the right approach, one that would be humane and civilized but would not try to escape from the past. We have to try to face our own past, to name it, to draw conclusions from it, and to bring it before the bar of justice. Yet we must do this honestly and with caution, generosity and imagination. There should be a place for forgiveness wherever there is confession of guilt and repentance.” Transitional Justice: Country Studies v.2: How Emerging Democracies Reckon with Former Regimes: Country Studies…Dec 1996 by Neil J.

Jewish tradition holds that the work of this season – teshuvah – requires us to bring to mind the harsh realities of our failings, to go through a process that ends with us no longer held back by the pain or the shame or the fear of what we have done, and to move forward in our lives. We leave behind, concealed from view but not forgotten or denied, the actions and inaction that stained our souls, that had imprisoned us. This is what we are doing here today, it is what the Jews of this community were doing when this synagogue was built. While some of the language may have altered and some of the prayers been edited, Rabbi Pinchas Halevy Horowitz would recognise what we are doing were he to join us today. As would those whose names are inscribed on the walls, and all the Jews of the generations between the two. We are joined to them by the liturgy of this day, by the shared understanding of the meaning and work of this season, by the timelessness of the tradition that speaks of repentance and return to God, of forgiveness and of moving on, of not denying the past but not being held captive to its power.

The Jews who came before us are held with us in a chain of tradition, their wisdom and experience passed on through the generations and through the communities which welcome people into Judaism We in modernity will one day pass into history, leaving behind a name, some family stories, some wisdom and some love, maybe some descendants, and hopefully a physical memorial of some kind. On that memorial will no doubt be the acronym also found on the walls of this synagogue over the names of those Prague Jews taken and murdered in the camps  ת’נ’צ’ב’ה  It is taken from a verse in Samuel via the memorial prayer and which speaks of the soul being bound up in the bundle of life, an image rather like an unending piece of fabric or carpet, in which the souls of those who came before are part of the weave, necessary to anchor and to hold the structure which will go on being woven as new souls come into the mix. In this image, the lives of those who came before are an integral part of the fabric of our lives, as our lives will help shape the world of those to come. And this knowledge brings both a sense of rootedness and of responsibility to those who came before and to those who will come after.

For the fabric to be strong, the lives must be connected, and even when one thread physically ends, its existence provides the anchor for the later ones. For that anchor to be solid, there must be regular teshuvah, the reflection and balance, the bringing to mind and naming of what went wrong in order to face it, to learn and understand, to apply compassionate and proper justice, and to bring about a conclusion, an end to the pain or bitterness or anger in order to let go, to cover over and to move on with the weave. Whether that image is about each of our individual lives, or scaled up to the life of a family or of the Jewish people as a whole, the lesson and the work remains the same. We reflect and remember, we admit and repent, we try to repair, we do our best to make good, and then we let go and go out into life ready to write on a new page of our Book of Life.

Our Rosh Hashanah Liturgy quotes not only the psalmist but also Isaiah (65:16-17) who describes God as saying “So that the one who blesses in the earth shall bless by the God of truth; and the one that swears in the earth shall swear by the God of truth; because the former troubles are forgotten, and because they are hid from Mine eyes. For now I create new heavens and a new earth, and the past need not be remembered, nor ever brought to mind. Be glad and rejoice in what I can create.”

The work of remembering, of making transparent, of repenting and repairing and of letting go in order to go move on is holy work. The Kesseh or Kapparah of this season mirrors the divine work of creation. This season is the season of penitence in which we wear white; Yom Kippur a joyful fast rather than a time of misery and gloom. The sound of the shofar reminds us of the work we do alongside God, the concealment and covering of a reasonably resolved past nudges us forward to do the work God expects from us. We are tied into the past and we honour from where we came. We are tied into the future, and in order to help bring about the best one we can, we are here together. As links in the shalshelet haKabbalah, the chain of tradition, the golden thread that brings us close to all who prayed the Rosh Hashanah liturgy, it is our turn to Remember, to Repair, to Repent, and to Return. May all who came before us bless us, and may we in turn be a blessing to those who journey with us and those who come after.
