Brothers, need your help to Counter a confusing doctrine. Please share your views.

Brothers, I have recently seen a post in many of Christian Facebook pages, mentioning Bapitism in the name of Jesus alone is valid. That person who posted that content only by selectively upholds acts 2.38. He also says that Matthew 28.19 has been said to apostles, but not to us. He also says that we should only listen to apostles said in acts 2.38 (Baptism on Jesus’s name). He also says acts 2.38 Baptism is only valid Baptism.

That person also denies the Trinity (Seperate mentioning of personalities of Trinity).
