There are many, very thorough Evangelical studies of each one of these issues and to what extent the Early Chuch believed in transubstantiation, infant baptism, the perpetual virginity, sinlessness and assumption of Mary, the papacy, the Catholic OT cannon and other issues.
A good summary is here:

The Christian church of the first three centuries was “catholic”, in the sense of being universal, but certainly not Roman Catholic.
By the way, you know that other branches of Christianity accept the trinity and divinity of Christ. I think both of these dogma were accepted by the disciples and are found in the Bible.
That website was nothing but speculation, bias, unhistorical and unreliable that it seriously throws doubt on what they “assume” they know about church history. But what else could they say, since they deny Catholicism? They “naturaly” have to twist and turn, distort and delude the obvious truths about the eraly christians. Because the early christians were not protestant.
It is very true that the church fathers didn’t agree entirely on every single doctrine, 100% all the time. Besides, the Church was in her youth. But the early fathers were much closer to the Catholic Church of today than the Protestant Church of today or of any day.
Apostolic Tradition:
Papias
“Papias [A.D. 120], who is now mentioned by us, affirms that he received the sayings of the apostles from those who accompanied them, and he, moreover, asserts that he heard in person Aristion and the presbyter John. Accordingly, he mentions them frequently by name, and in his writings gives their traditions [concerning Jesus]. . . . [There are] other passages of his in which he relates some miraculous deeds, stating that he acquired the knowledge of them from tradition” (fragment in Eusebius, *Church History *3:39 [A.D. 312]).
Eusebius of Caesarea
“At that time [A.D. 150] there flourished in the Church Hegesippus, whom we know from what has gone before, and Dionysius, bishop of Corinth, and another bishop, Pinytus of Crete, and besides these, Philip, and Apollinarius, and Melito, and Musanus, and Modestus, and, finally, Irenaeus. From them has come down to us in writing, the sound and orthodox faith received from tradition” (*Church History *4:21).
Irenaeus
“As I said before, the Church, having received this preaching and this faith, although she is disseminated throughout the whole world, yet guarded it, as if she occupied but one house. She likewise believes these things just as if she had but one soul and one and the same heart; and harmoniously she proclaims them and teaches them and hands them down, as if she possessed but one mouth. For, while the languages of the world are diverse, nevertheless, the authority of the tradition is one and the same” (*Against Heresies *1:10:2 [A.D. 189]).
“That is why it is surely necessary to avoid them [heretics], while cherishing with the utmost diligence the things pertaining to the Church, and to lay hold of the tradition of truth. . . . What if the apostles had not in fact left writings to us? Would it not be necessary to follow the order of tradition, which was handed down to those to whom they entrusted the churches?” (ibid., 3:4:1).
…
"It is possible, then, for everyone in every church, who may wish to know the truth, to contemplate the tradition of the apostles which has been made known throughout the whole world. And we are in a position to enumerate those who were instituted bishops by the apostles and their successors to our own times—men who neither knew nor taught anything like these heretics rave about.
"But since it would be too long to enumerate in such a volume as this the successions of all the churches, we shall confound all those who, in whatever manner, whether through self-satisfaction or vainglory, or through blindness and wicked opinion, assemble other than where it is proper, by pointing out here the successions of the bishops of the greatest and most ancient church known to all, founded and organized at Rome by the two most glorious apostles, Peter and Paul, that church which has the tradition and the faith which comes down to us after having been announced to men by the apostles.
“With this church, because of its superior origin, all churches must agree—that is, all the faithful in the whole world—and it is in her that the faithful everywhere have maintained the apostolic tradition” (ibid., 3:3:1–2).
