As a contributor to the 2013 Anglican Pilling Report on human sexual ethics Father Radcliffe said of homosexuality:
How does all of this bear on the question of gay sexuality? We cannot begin with the question of whether it is permitted or forbidden! We must ask what it means, and how far it is Eucharistic. Certainly it can be generous, vulnerable, tender, mutual and non-violent. So in many ways, I would think that it can be expressive of Christ’s self-gift. We can also see how it can be expressive of mutual fidelity, a covenantal relationship in which two people bind themselves to each other for ever.
Father Radcliffe often celebrated Mass for the U.K. dissident group Soho Masses Pastoral Council (now renamed the LGBT Catholics Westminster Pastoral Council).
