"Your thoughts?"
I think I've seen much better arguments than this! I will say that the appropriate canonical position of the Pope is that of first in honor, the primus inter pares not simply the "primus". When a Pope is elected who teaches the The Faith in all its fullness as preserved in the Orthodox Church and lived out by the People of God, then the proper canonical order will be restored...but not before that.
What were they?
Of course you have,this was just frosting on the cake. The ingredients,directly from scripture,that comprise the cake are:
Mt.16:15-19; 1Cor.15:3-5; Gal.1:18; Is.61:1-2; Is.22:15-25;Rev.3:7;Acts 2:14-36; Lk.22:31-32;Acts 15; Mt.10:2-4;Acts 12:5; Jn. 21:15-17; Mt.17:24-27; Mt.14:28-31; Mk.16:7; Acts 4:8-12; Acts 5:3-11; Acts5:15; Acts8:9-25; Acts 9:32-35.
I hope after reading these passages you will understand how inconceivable it is for an informed Roman Catholic to understand how any non-Roman Catholic can argue Christ's intention to establish a visible Church with a visible leader.
