Early over the course of AP Irenaeus claims that God is Father to the faithful '[…] since "in the last times" he opened the testament for the adoption as sons; while to the Jews He is as Lord and Lawgiver […]'. Crucially, this claim frames the Christian understanding of God according to a Trinitarian pattern, and one which passes necessarily through Jesus. This, follows, insofar as in him the new testament “was opened”, and only with respect to the only begotten and incarnated Son we can understand God as the Holy Trinity and ourselves as adopted sons. Hence, Jesus establishes the conditions for understanding the Old and the New Testament as in continuity with one another, as well as the God of Israel in a Trinitarian way.
