If you believe that some of the groups you've mentioned would subscribe to the Apostle's Creed, then your understanding of this creed or those groups is flawed.
You should know that while recitation of the Apostle's Creed is not salvific, neither is my telling you that I trust in Christ as my Lord and Savior. Regardless, none of this has any bearing on your refusal to address the offense I've brought to your attention.
What "offense" is that?
