Only a Catholic can have a conscience
In an article published by L’Osservatore Romano, Stefan Heid, professor of liturgy and hagiography at the Pontifical Institute of Christian Archeology, said “according to the judgement of the early Church, ecclesiastical celibacy has dogmatic relevance...When Jesus spoke of the eunuchs for the sake of the Kingdom of Heaven [for example], it was understood as perfect continence for all of the disciples, regardless of whether or not the Apostles were married.”
Pope Francis also said that God would forgive atheists, as long as they “live according to their consciences.” What the pontiff fails to say is that all people have a duty to achieve an informed conscience, but this can only be through Catholic teaching.
