Athanasius Moment?

Cafeteria Catholics (Liberals!) dissent on basic Church teachings such as those on abortion, contraception, euthanasia, the all-male priesthood, and even the Real Presence of Christ in the Eucharist. Liberalism is so rampant in the Church today that it threatens to overwhelm its traditions, much as the Arian heresy threatened the Church in the 4th century. Does the Church need another Athanasius moment?
