Christ being our doctrine is confirmed in the scriptures, particularly in 1 John 2:24, where abidance in the doctrine of Christ equates to having both the Father and the Son.
Christ stands central to our faith as the embodiment of our doctrine. 1 John 2:24 asserts that those who abide in the doctrine of Christ also possess both the Father and the Son, reinforcing the truth that our entire understanding of God is rooted in the person and work of Jesus Christ. This doctrine is not merely a set of beliefs but a relationship with Jesus Christ who is the true revelation of God. The high priest's inquiry about Jesus' disciples and doctrine reflects the necessity for authentic testimony; any claim to know God must be grounded in a true understanding of Christ. This is a vital aspect of historic Reformed theology that asserts our knowledge of God is contingent upon His revelation through Jesus.
