The immaculate conception cannot be true because, if the Theotokos is without ancestral sin, then Christ's sacrifice was not necessary to be without ancestral sin.
I know less about Marian theology, but papal infallibility was always part of the Catholic Church, it just wasn't completely defined until Leo VIII clarified in the 1800s. The successor of St. Peter, given leadership by Christ, has always been the leading authority on matters of doctrine in the Catholic Church.
Then why did they never use this until the 1800's? Papal primacy existed always and even supremacy in the West, but infallibility? It was totally foreign to the early Church outside of the Ecumenical Synods.
