Trinity (God the Father, Son Christ & Holy Spirit)
All present together at the same time. Matt.3:16-17, Luke 3:21-22
The (Holy) Spirit descended from heaven, as a dove, and remained on Christ. John 1:32 There are three that bear witness in heaven: The Father, the Word (Christ described John 1:1),
and the Holy Spirit; and these three are one. There are three that bear witness on earth: The Spirit, the water and the blood; and these three agree as one. 1st John 5:7-8
