What does the Bible say about the unity of the Father and the Son?

The scripture declares that Jesus Christ stated, 'I and my Father are one' (John 10:30). This profound declaration articulates the essential and eternal unity between Christ and the Father. It signifies not merely a likeness in purpose or will but a complete oneness in essence, attributes, and authority. The surrounding audience, notably the Jews, recognized the gravity of His words as they attempted to stone Him for what they perceived as blasphemy; they understood that He was claiming equality with God. Thus, this assertion becomes a cornerstone of Christian belief, affirming the doctrine of the Trinity where the Father, the Son, and the Holy Spirit are one in nature and purpose.
