A few comments from my perspective:
a.) Was founded by Christ personally
b.) Has existed continuously since the time of Christ;
I would think, “has existed continuously, unchanged, since the time of Christ” would be more correct. That being said, I would say changes, even contradictions, have occurred numerous times in the Catholic Church’s history, which make me doubt the applicability of this statement to the Catholic church, or the understanding of exactly what “the church” is.
c.) Is Catholic or Universal, in accordance with Christ’s command to go to all the the world and teach all nations;
d.) Demands that all her members admit the same doctrine;
Paul seems to have no problem with differences, even in doctrine, to a pretty liberal extent.
e.) Exercises Divine authority over her subjects, since Christ said that if a man would not hear the Church he would be as the heathen.
Who is the “her” in this statement? The leadership? The laity? Who wields this authority? Jesus is speaking to Peter and the Apostles, the “first Pope,” and Bishops. Why would they, of all people, have to appeal to a higher authority in “the church?”
