What Do Christians Confess?

Just a question: if Christians get upset when “progressives” update the Creed to say things like “Mother-Father” “Jesus Christ, God’s only Child” and baptize people in the name of the “Creator, Redeemer, and Sanctifier” why don’t some of these same Christians take equally seriously the statement in the final part of the Nicene Creed that Christians “believe in one Baptism for the remission of sins.” If the progressives have given up an essential part of Christian doctrine, why have the anti-Sacramentalists not given up something at least as equally fundamental?

The “one, holy, Christian [catholic], and apostolic Church” that we confess is the same Church that confesses faith in “one Baptism for the remission of sins.” Have you not put yourself outside of your own Christian Faith if you deny it?
