Why have I started lecturing people in the streets? Maybe because I consider it a form of public service

You’ve got to hand it to Jesus. He didn’t settle for the easy part of being a rabbi, turning up to charity fund raisers or telling folksy parables about the wise man of Minsk to bored barmitzvah boys. He went out, in Matthew’s words, “to cities”, or wandered by the sea shore where “great multitudes were gathered unto him”. I have started to do the same. “Lecturing,” I call it. Addressing people in the streets on matters of practical morality, dress sense, litter – that sort of thing.
