Rayner was ordained in the Liberal Jewish ministry on 21 June 1953 and served the
South London Liberal Synagogue, in
Streatham until 1957. He then worked at St John's Wood Liberal Synagogue until in 1963 he left for
Cincinnati, Ohio, in the United States. Rayner had been invited to the
Hebrew Union College to take up a graduate fellowship. He returned to the UK to serve as Minister at the
Liberal Jewish Synagogue in June 1965. He wrote books on diverse topics including
halakha, marriage,
ethics,
Zionism,
theology and
Jewish-Christian relations. He also gave a large number of sermons. He was voted one of the best preachers in Britain by
Harpers and Queen magazine in 1976. During the late 1960s and 1970s Rayner made several appearances on national television and radio. Working with American Rabbi Chaim Stern, Rayner was the main liturgist of British
Liberal Judaism. They compiled the Sabbath and Festivals and High Holidays liturgy used by all Liberal Synagogues, Service of the Heart and Gates of Repentance, continuing their editorial partnership to co-edit Siddur Lev Chadash. He was the teacher of liturgy at
Leo Baeck College in London. He was an active participant in
inter-faith work as co-chairman of the London
Society of Christians and Jews. As a result of this work in 1993 he was appointed a
