Fr Leonard Feeney is undoubtedly one of the most polarising figures in the history of the American Church. Having died in 1978, he is still well-known for his strict interpretation of extra Ecclesiam nulla salus: “outside the Church there is no salvation”. Broadly speaking, “Feeneyism” is the belief that, unless one is baptised with water and the Trinitarian formula, there is no hope of going to heaven. But the details of this theological debate are complex, and continue to be hashed out even today.
