Athanasius of Alexandria (A.D. 297 – 373) Bishop of Alexandria, was a chief theologian and early Church Father of the Christian faith. To this day he is widely respected within Western Christianity, Eastern Orthodoxy, and Roman Catholicism. As a staunch Trinitarian, Athanasius spent much of his life battling against the groundwork laid by his predecessor, Arius, a non-Trinitarian. In his writings Against the Heathen, Orations Against the Arians, and The Incarnation of the Word of God, Athanasius stresses the urgency of holding to the faith proclaimed by the apostolic teachings of Scripture. Historically he has been credited as being the first person to identify the same twenty-seven books of the New Testament that are familiar to Christians today.
"We have dealt thus far with the Incarnation of our Savior, and have found clear proof of the resurrection of His Body and His victory over death. Let us now go further and investigate the unbelief and the ridicule with which Jews and Gentiles respectively regard these same facts. It seems that in both cases the points at issue are the same, namely the unfittingness or incongruity (as it seems to them) alike of the cross and of the Word’s becoming man at all. But we have no hesitation in taking up the argument against these objectors, for the proofs on our side are extremely clear.
After him the prophets also give their witness, saying, “But I as an innocent lamb brought to be offered was yet ignorant of it. They plotted evil against Me, saying, ‘Come, let us cast wood into His bread, and wipe Him out from the land of the living.” [Jeremiah 11:19] And, again, “They pierced My hands and My feet, they counted all My bones, they divided My garments for themselves and cast lots for My clothing.” [Psalm 22:16-18] Now a death lifted up and that takes place on wood can be none other than the death of the cross; moreover, it is only in that death that the hands and feet are pierced. Besides this, since the Savior dwelt among men, all nations everywhere have begun to know God; and this too Holy Writ expressly mentions. “There shall be the Root of Jesse,” it says, “and he who rises up to rule the nations, on Him nations shall set their hope.” [Isaiah 11:10]
