Ignatius, a bishop of Antioch during the reign of the Emperor Trajan (98–117 A.D) and martyr in Rome at end of the reign of Trajan ca. 115 A.D, records one of the earliest understanding of the person and the work of Christ Jesus. In the opening of his letter to the Smyrnæans he wrote:
I give glory to Jesus Christ the God who bestowed such wisdom upon you; for I have perceived that ye are established in faith immovable, being as it were nailed on the cross of the Lord Jesus Christ, in flesh and in spirit, and firmly grounded in love in the blood of Christ, fully persuaded as touching our Lord that He is truly of the race of David according to the flesh, but Son of God by the Divine will and power, truly born of a virgin and baptized by John that all righteousness might be fulfilled by Him, truly nailed up in the flesh for our sakes under Pontius Pilate and Herod the tetrarch (of which fruit are we—that is, of His most blessed passion); that He might set up an ensign unto all the ages through His resurrection, for His saints and faithful people, whether among Jews or among Gentiles, in one body of His Church.
If I argued that this is one of the earliest well outlined Christology, would I be wrong?
