2 Corinthians 13:14 note 1
141 The grace of the Lord is the Lord Himself as life to us for our enjoyment (John 1:17 and note 1; 1 Cor. 15:10 and note 1), the love of God is God Himself (1 John 4:8, 16) as the source of the grace of the Lord, and the fellowship of the Spirit is the Spirit Himself as the transmission of the grace of the Lord with the love of God for our participation. These are not three separate matters but three aspects of one thing, just as the Lord, God, and the Holy Spirit are not three separate Gods but three "hypostases...of the one same undivided and indivisible" God (Philip Schaff).
...Just before He was crucified in the flesh and resurrected to become the life-giving Spirit (1 Cor. 15:45), He unveiled His mysterious trinity to His disciples in plain words (John 14—17), stating that the Son is in the Father and the Father is in the Son (John 14:9-11), that the Spirit is the transfiguration of the Son (John 14:16-20), that the three, coexisting and coinhering simultaneously, are abiding with the believers for their enjoyment (John 14:23; 17:21-23), and that all that the Father has is the Son's and all that the Son possesses is received by the Spirit to be declared to the believers (John 16:13-15). Such a Trinity is altogether related to the dispensing of the processed God into His believers (John 14:17, 20; 15:4-5) that they may be one in and with the Triune God (John 17:21-23).
...In the Divine Trinity all the believers, both Jewish and Gentile, have access unto God the Father, through God the Son, in God the Spirit (Eph. 2:18). This indicates that the three coexist and coinhere simultaneously, even after all the processes of incarnation, human living, crucifixion, and resurrection.
