三一神─神聖三一的三者─乃是自有永有、同時存在並且互相內在；因此，父、子、靈就是一個神聖奧秘的範圍，神聖三一的三者住在彼此裡面─太二八19，林後十三14。

The Triune God—the three of the Divine Trinity—is self-existing, ever-existing, coexisting, and coinhering, and as such, the Father, the Son, and the Spirit are a divine and mystical realm, with the three of the Divine Trinity dwelling in one another—Matt. 28:19; 2 Cor. 13:14.

按照約翰十四章十至十一節，子在父裡面，父在子裡面；這指明父具體化在子裡面，而子是父的具體化身，形成神聖奧秘的範圍，就是三一神的範圍。

According to John 14:10 and 11, the Son is in the Father, and the Father is in the Son; this indicates that the Father is embodied in the Son and the Son is the Father's embodiment, forming a divine and mystical realm, the realm of the Triune God.
