Resty as you know the Trinity is mentioned in the Bible..
God the Father is the First Person of the Trinity
God the Son, the Word, the LORD Jesus Christ is the Second Person of the Trinity..
God the Holy Ghost, the Holy Spirit is the Third Person of the Trinity..
no man could have dreamed the Trinity up...
after all no Mormon leader has ever been able to explain the Trinity of God...
that’s why Mormons have denied God from Joey Smith on down...
