The doctrine of the Trinity is shown in Matthew 28:19, where
Jesus instructs the apostles: "Go therefore and make disciples of
all nations, baptizing them in the name of the Father and of the
Son and of the Holy Spirit."
The parallelism of the Father, the Son, and the Spirit is not
unique to Matthews Gospel, but appears elsewhere in the New
Testament (e.g., 2 Cor. 13:14, Heb. 9:14), as well as in the
writings of the earliest Christians, who clearly understood them in
the sense that we do today, that the Father, the Son, and the
Spirit are three divine persons who are one divine being (God).
