Re: The Early Christians: Creed, Confession and Scripture

He who holds immovable in his heart the plumb line of the truth, which he 
took hold of through baptism, is able to see through all deceptions of 
false teachers.

A spiritually minded disciple has the constant help of faith in the one 
God, of firm conviction about Christ, and of true recognition of the Holy 
Spirit. This teaching of the apostles is the age-old fellowship of the 
church throughout the whole world.

The church spreads out over the whole world to the uttermost ends of the 
earth. From the apostles and their disciples she received the faith: in
the 
one God, the almighty Father, creator of heaven and earth, the sea, and
all 
that is in them; in the one Christ [Messiah] Jesus, the son of God, who
for 
our salvation took on flesh; and in the Holy Spirit who through the 
prophets proclaimed God’s plan of salvation and the twofold coming of the 
Lord, his birth from a virgin, his suffering, his resurrection from the 
dead, the bodily ascension into heaven of our beloved Lord, the Christ 
[Messiah] Jesus, and his future coming from the heavens in the glory of
the 
Father "to make all things new" and to raise up anew all flesh of the
whole 
human race in order to execute judgment justly on all.
