Why is Jesus called the Father’s “only Son?” (Q52)
From To Be A Christian, An Anglican Catechism
Jesus alone is God the Son, co-equal and co-eternal with God the Father and God the Holy Spirit. He alone is the image of the invisible Father, the one who makes the Father known. He is now and forever will be incarnate as a human, bearing his God-given human name. The Father created and now rules all things in heaven and earth “through Jesus Christ our Lord.” (Colossians 1:15; Hebrews 1:1-5; John 1:18)
