Doctrinal resources explaining why the Catholic Church cannot ordain women.
‘The Catholic Priesthood and Women: A Guide to the Teaching of the Church’ by Sara Butler, MSBT. The definitive guide by a former supporter of female ordination. Sister Butler’s guide is intended for priests and laity. Note to Catholic feminists: this is written by a female theologian who no longer supports female ordination.
Catechism of the Catholic Church, #1577: “Only a baptized man validly receives sacred ordination. The Lord Jesus chose men to form the college of the twelve apostles, and the apostles did the same when they chose collaborators to succeed them in their ministry. The college of bishops, with whom the priests are united in the priesthood, makes the college of the twelve an ever-present and ever-active reality until Christ’s return. The Church recognizes herself to be bound by this choice made by the Lord himself. For this reason the ordination of women is not possible.”
