GOD IS THREE PERSONS - THE FATHER, THE SON (JESUS CHRIST) AND THE HOLY SPIRIT (THE TRINITY).
One needs to accept and believe in God’s Truth and not man’s truth and live with with Faith and Trust in our Creator.
Jesus established His Church with 7 Sacraments, including the Eucharist as Hi Body and Blood for our salvation.
One can either accept or reject God, as God gives us the complete freedom to do so and the graces to fully accept His Truth.
