The 1950s saw OICCU at perhaps its greatest numerical strength, while the SCM was seen to have moved towards Marxism. One leading figure at this time was Michael Green (President in 1952), who has been a leading evangelical in the Church of England and then the Anglican Communion since the 1960s. Green has taken a particular interest in promoting the Charismatic Movement, including within OICCU.
