The Father, His Son Jesus Christ, and the Holy Spirit; the only true God.
God's Word. The only record of God's revelation to mankind.
The only Son of God and the only Name by which we must be saved.
Is only "saving faith" if it includes belief in the gospel message, repentance from sin, confession of Jesus Christ as Lord and Savior, and being immersed for the remission of sin.
The Church of Christ:
We are not the only Christians, but in name Christians only.
