The doctrine of the Trinity is not a logical exercise or a dogmatic excursion. It’s central to our salvation. The Triune God is our Creator, Redeemer, and Sanctifier. Lose this doctrine, and as the Creed says, you lose it all. A Jesus who is less than God is also less than Savior. Today we see that Christ has given his church one mission with one means, a mission and means that reflect the nature of the one true God. God sends his church out into the world so that all people would again enjoy the fellowship enjoyed between Father, Son, and Holy Spirit.
