The early Church and apostles predominantly preached the same God as depicted in the Old Testament, shaped by their Jewish background. Their understanding of the Christ was also rooted in Jewish tradition. Initially, there was no notion among Jews that God would become the Christ. When some began preaching modalism in the second century, a concept where the Father transforms into the Christ, it faced opposition from many Christians who found it unfamiliar and divergent from the gospel they knew. Most early Christians adhered to the teachings of the apostles, which did not include the belief that the Father became the Christ.
