Let me ask you this: when Jesus confronted Satan in the wilderness, did He appeal to the authority of scripture by saying “it is written…” or did He appeal to the authority of the Catholic church by saying “the Catholic church has declared…”?
Well, first of all, I don’t see how it would ever be proper to say that Christ appeals to the authority of his Church; rather, and much more appropriately, it is his Church which appeals to the authority of Christ.
Second, in the same “wilderness” passage to which you alluded, as well as in every other passage where Christ speaks, he appeals, ultimately,
not to the Scriptures themselves as the final authority, but *to himself and his own infallible interpretation *of those same Scriptures as being
final and binding on all consciences.
Thus the focus is, very much as it always should be, * on Christ*, and never a book, inspired or otherwise.
Clearly then there is absolutely no analogy whatsoever to be draw between Christ’s
absolute and infallible use of Scripture and that of the confused, contradictory, fallible, and non-binding opinions of the countless Protestant sects.
Christ alone was the infallible interpreter of Scripture, whether in his confrontation with Satan or in his disputes with the Jews.
And *nowhere *do we find him ever authorizing anyone to “privately interpret” the Sacred Texts. Not even to his own apostles did he grant such authority!
He did however, give power and authority to his one Church, the “pillar and foundation of the truth” (1 Tim 3:15) so that it might “teach, govern, and sanctify all men,” and this, “in the church by Christ Jesus
throughout all ages, world without end.” Eph. 3:21
Then Jesus came to them and said, “All authority in heaven and on earth has been given to me. 19Therefore go and make disciples of all nations, baptizing them in[a] the name of the Father and of the Son and of the Holy Spirit, 20and teaching them to obey everything I have commanded you. And surely I am with you always, to the very end of the age.” Matt. 28:18-20
So Christ founded only
one Church. And he promised to be with this one Church until the end of time. Of this one Church St. Augustine speaks:
Furthermore, the Catholic Church alone is the body of Christ, of which He is the Head and Saviour of His body. Ephesians 5:23 Outside this body the Holy Spirit gives life to no one seeing that, as the apostle says himself, “The love of God is shed abroad in our hearts by the Holy Ghost which is given unto us;” Romans 5:5 but he is not a partaker of the divine love who is the enemy of unity. Therefore they have not the Holy Ghost who are outside the Church; for it is written of them, “They separate themselves being sensual, having not the Spirit.” Jude 19 But neither does he receive it who is insincerely in the Church, since this is also the intent of what is written: “For the Holy Spirit of discipline will flee deceit.” Wisdom 1:5 If any one, therefore, wishes to receive the Holy Spirit, let him beware of continuing in alienation from the Church, let him beware of entering it in the spirit of dissimulation;
