The Pope is only infallible when he speaks ‘ex cathedra’ – i.e. when pronouncing on doctrinal matters of faith as Pontifex Maximus. So, last week, when Francis privately told a gathering of bishops that he opposed the ordination of homosexual priests because there was too much ‘frociaggine’ – or ‘faggotry’ – in the priesthood already, he was not speaking formally as the Vicar of Christ.
