Pope spells out the Church’s basic position
Some people are dismayed that the document states: “According to Catholic doctrine, (Protestant) communities do not enjoy apostolic succession in the sacrament of orders, and ... therefore, (with no) sacramental priesthood, have not preserved the genuine and integral substance of the Eucharistic Mystery (and therefore) cannot, according to Catholic doctrine, be called ‘churches’ in the proper sense”.
Protestant commentators note that Christ — not the Pope — is the head of the church. The Catholic Church, however, has never taught that the Pope is the head of the church.
