The Trinitarian baptismal formula in Matthew 28:19 was developed much later and is not original to the Gospel of Matthew.

Dr. Jamal Badawi and Victor Paul Wierwille argue that the absence of the Trinitarian baptismal formula in Eusebius's writings prior to the Council of Nicea indicates that it was a later addition to the Gospel of Matthew. However, this argument is based on silence and does not account for the possibility that Eusebius simply had no reason to cite it before the Council. The lack of quotation does not imply ignorance of the formula's existence. Furthermore, numerous early Christian writings, including those from the disciples of the Apostles, reference the Trinitarian formula, demonstrating its use well before the Council of Nicea. These early texts suggest that the formula was widely known among Christians, to the extent that writers felt no need to specify its source, indicating its established presence in the Gospel of Matthew. The Didache, or Teaching of the Twelve Apostles, is one such document that predates the Council and supports the existence of the Trinitarian formula. Its discovery and subsequent analysis reveal that early Christians were indeed familiar with the baptismal command as recorded in Matthew 28:19, further affirming the formula's authenticity and continuity in Christian practice.
