Athanasian Creed~excerpt

The Athanasian Creed is named after St. Athanasius, a staunch defender of the Christian faith in the Fourth Century. It was prepared to assist the Church in combating two errors that undermined Bible teaching. One error denied that God's Son and the Holy Spirit are of one being or Godhead with the Father. The other error denied that Jesus Christ is true God and true man in one person.
The Athanasian Creed continues to serve the Christian Church as a standard of the truth. It declares that whoever rejects the doctrine of the Trinity and the doctrine of Christ is without the saving faith. At the same time the Church boldly proclaims her confidence in the mystery of the triune God, the Holy Trinity who has given himself for our salvation.
