This is going to be a work-in-progress, but I invite everyone's participation, but please, preserve the numbering! Here are five of mine (not in any order of significance):
1) That the Church of Christ does not subsist fully, absolutely, and uniquely in the Holy Roman Catholic and Apostolic Church. Condemned as heretical and false.
2) That the Church of Christ is not the Holy Roman Catholic and Apostolic Church. Condemned as heretical and false.
3) That the Mystical Body of Jesus Christ, the sole God Incarnate, is not "one and the same" with His Bride, the Holy Roman Catholic and Apostolic Church. Condemned as heretical and false.
4) That women could be ordained to the Sacrament of Holy Orders at any time in the past or future. Condemned as heretical and false.
5) That the Sacrament of Matrimony to be valid does not require the union of one man with one woman. Condemned as heretical and false.
Okay, keep going with #6.
