Why the Father is typically called simply God in the NT while Jesus is called the Son: guarding against modalism

Mike first affirms that all three persons — Father, Son, and Spirit — are explicitly called God at various points in Scripture. The reason Jesus is more carefully delineated as the Son rather than simply God throughout the NT is contextual: in first-century Jewish thought, repeatedly calling Jesus God without qualification would lead people toward modalism — the error that the Father became the Son who then became the Spirit. The NT writers are being careful to distinguish the personhood of the Son from the Father while still teaching his deity.
