Trinity and redemption are the two basic tenets of Christianity. According to relevant public information, Christianity is the collective name for all sects that believe in Jesus Christ as the savior, and is also known as the Christian religion. One of the basic tenets of Trinitarian Christianity is the belief that God is one but in three persons, namely the Father, the Creator and Lord of heaven and earth. The Son - Jesus Christ, the Son of God, was sent by God and was born as a human through the virgin Mary. He became flesh, died, resurrected, and ascended to heaven. He redeemed all mankind and will surely come again to judge the world. Holy Spirit – God the Holy Spirit. The three are one entity, but have three different persons.
