I attended an international Jewish conference in Australia a few years' ago, rabbis of all stripes in attendance. The guest of honour was an eminent rabbi from a far-away country, who spoke with rare humility and insight. I managed to wangle a seat near him at lunch, and had a lively conversation with him. I liked him very much.
That Friday evening, Kabbalat Shabbat was celebrated in a beautiful, modern synagogue. Beautiful, but - from my perspective - jarring: shaped like a Greek amphitheater, the seats upholstered in a violent red, people sitting high above the bimah, higher than the service leaders, higher than the Ark where the Torah scrolls are kept, the repository of teachings guiding a Jewish life. The service included an entire pop band. No time, no space for reflection. Uncomfortable, I peeked at the Rabbi, sitting some distance away. He was still, attentive. I tried to calm my restlessness, resisting the urge to leave.
Following the service, dinner was served to everyone in the elegant dining room. After the meal, as I crossed the room to visit a friend sitting elsewhere. I met the Rabbi, who put his arm round my shoulders and said quietly: "How are you feeling?"
"Like a fish out of water," I whispered.
"So do I."
I've wondered if he regretted speaking so openly, but it's a moment I remember with affection, for his trust. Or had he noticed my restlessness during the service? Was this a gentle way of reproving me: "Feel like a fish out of water, but don't judge..."
I managed to find him on his own the next day and quickly gave him a copy of my novel, There was a garden in Nuremberg.
. 
I also gave him the address of our congregation. He warned me not to expect a visit. Understandably: such a small congregation, so far away.
Three years later, he's on Youtube, again a guest of honour, lecturing at an institution of interfaith study in Boston. I recognise the simplicity with which he tells how once upon a time, in his homeland a Cardinal organised an interfaith gathering.
I'd heard of this eminent Cardinal, who once said, "Who am I to judge?"
That meeting became an important event for the Rabbi, for he requested that the Cardinal become his teacher.
The Rabbi said: "He became my Rabbi."
