按照〔神格的三者〕的素质，三者乃是一；因此，有素质之三一的一面。子是父的具体表现，（西二9，）灵是子的实际。（约十四16～18。）
在圣经里这样的话，有力的证明父、子、灵在素质上乃是一。
主在约翰十章三十节说，‘我与父原是一。’祂不是说，‘我与父是合一的。’我们可以说，我们彼此合一。但主耶稣与父，祂们二者乃是一。在约翰福音里，有一个奥秘的观点，给我们看见父在子里面，子在父里面。毫无疑问的，祂们二者也在灵里面，灵也在祂们里面。这是素质的一面。
According to the essence (the three of the Godhead), the three are one; therefore, there is an aspect of the essential Trinity. The Son is the embodiment of the Father (Col. 2:9), and the Spirit is the reality of the Son (John 14:16-18).
Words like this in the Bible strongly prove that the Father, the Son and the Spirit are essentially one.
In John 10:30 the Lord said, “I and the Father are one”, he didn’t say, “I am one with the Father”. We may say that we are one with each other. But the Lord Jesus and the Father, the two of them are one. In the Gospel of John there is a mystical viewpoint showing us that the Father is in the Son and the Son is in the Father. Undoubtedly, both of them are also in the spirit, and the spirit is in them. This is the essential aspect.
