Well, no: the gent spouting all of his reasons for leaving the Catholic faith is annoyingly arrogant. His brief self-instruction suddenly convinces him that a billion or so Catholics who have been thrilled with our connection to Our Lord for 2,000 years are now all wrong and he, magnificent he, is right.

Not only that, he couldn't wait to post his wonderful rightness before the whole world to tell us all how wrong we all are.

Poppycock.

His brief self-instruction suddenly convinces him that a billion or so Catholics who have been thrilled with our connection to Our Lord for 2,000 years are now all wrong and he, magnificent he, is right.

By that logic, there are just as many Muslims.

13Enter through the narrow gate. For wide is the gate and broad is the way that leads to destruction, and many enter through it. 14But small is the gate and narrow the way that leads to life, and only a few find it.
Matthew 7:13-14

Well, no: the gent spouting all of his reasons for leaving the Catholic faith is annoyingly arrogant.

Man; I hear ya!!

"One indeed is the universal Church of the faithful, outside which no one at all is saved, in which the priest himself is the sacrifice, Jesus Christ, whose body and blood are truly contained in the sacrament of the altar under the species of bread and wine; the bread (changed) into His body by the divine power of transubstantiation, and the wine into the blood, so that to accomplish the mystery of unity we ourselves receive from His (nature) what He Himself received from ours."

--Pope Innocent III and Lateran Council IV (A.D. 1215)

"We are compelled in virtue of our faith to believe and maintain that there is only one holy Catholic Church, and that one is apostolic. This we firmly believe and profess without qualification. Outside this Church there is no salvation and no remission of sins, the Spouse in the Canticle proclaiming: 'One is my dove, my perfect one. One is she of her mother, the chosen of her that bore her' (Canticle of Canticles 6:8); which represents the one mystical body whose head is Christ, of Christ indeed, as God. And in this, 'one Lord, one faith, one baptism' (Ephesians 4:5). Certainly Noah had one ark at the time of the flood, prefiguring one Church which perfect to one cubit having one ruler and guide, namely Noah, outside of which we read all living things were destroyed… We declare, say, define, and pronounce that it is absolutely necessary for the salvation of every human creature to be subject to the Roman Pontiff."

--Pope Boniface VIII, Bull Unam sanctam (A.D. 1302)
