By the spring of 1914, Ewart accepted the Oneness formula and became one of its leading advocates. He reached the conclusion that the singular “name” in Matthew 28:19 was Jesus Christ, and that the one true God who had revealed himself as Father, in the Son, and as the Holy Spirit was none other than Jesus Christ (a form of Modalistic Monarchianism). To support this view, he pointed to Colossians 2:9, which states that in Jesus dwells all the fullness of the Godhead bodily. Ewart explained his discovery to other Pentecostal ministers, some of whom rejected his teaching, but others enthusiastically embraced it.
