Are Protestants Christians? In the past occasionally, my video channel was trolled by so-called Christians who are actually Protestants. Why? I dunno. Yet, in replying to their prejudiced and irrational arguments, I cannot help but question what is a Christian and are Protestants Christians. I read a reply on Tradition-In-Action's website on this subject. I find their answer quite erudite/ cogent. And I agree with them. So here below is their reply to a Protestant who desires unity with Catholics. Your approach is based on feelings. A man’s position should be based on principles, since we are rational animals. This is particularly true when we discuss the Faith. There is no way for us to be united if we do not profess the same Creed. Now then, you Protestants deny many Catholic dogmas, such as Transubstantiation at the Mass and the Real Presence of Christ in the Eucharist; you deny the role of Our Lady in the birth, formation and redemption of Christ, and the dogmas related to her – the Immaculate Conception, Virgin before, during and after parturition, her Assumption to Heaven; further you deny the universal mediation of Most Holy Mary for all the graces that come from Heaven. You also deny the existence of Purgatory and the value of prayers for the souls that are there; you deny the intercession of the Saints before God; you deny the Infallibility of the Pope and the Petrine Primacy; many of your sects even deny the role of the Hierarchy of the Bishops; you further deny the unity of the teachings of the Holy Scriptures by transposing them into as many different versions and interpretations as you want, following your arrogant lunacy of admitting free examination of the Bible; because of this, in practice you deny that the Bible is inspired by the Holy Ghost. These are some of the differences that exist between a Catholic and a Protestant. Now then, when you consciously deny so many important truths and dogmas of the true Faith left to us by Our Lord Jesus Christ, you cannot be in His grace or be called a Christian. Protestants constructed a different spiritual reality that you call Jesus, which has nothing to do with the real Jesus Christ whose sole Mystical Body is the Catholic Church. So then, this Jesus you adore is not the Word Incarnate. This person is someone else quite different from Him. Just as the false god the Jews adore is not the True God but the Devil, although they pretend he is and use the name God (cf. Jo 8: 44-45), yours also is not Our Lord Jesus Christ but the Devil. Regarding the "miracles" you claim Protestants do, we believe that the ones that are not tricks by charlatan ministers in fact come from the Devil. In conclusion, we Catholics cannot be united with you Protestants unless you abjure all your heresies and officially adhere to the ensemble of dogmas of the Catholic Faith. Any other kind of "union" is the mirage of a false ecumenism that, with its total relativization of the truths of the Faith, is inexorably leading both Catholics and Protestants to Hell. We hope this answer will help you realize these truths and abandon your illusory feel-good saccharine heresy of universal salvation. For me, Nich of Fluh, I can only say QED.
