The issue is not whether the creed agrees with Scripture or not, but whether people look to the creed instead of Scripture as the authoritative Word.
I am glad God sent men that were bold to enough to investigate the claims of some, investigate Scripture, and work to make a united statement in defense of key doctrines. Like the faithful in Berea these too set a fine example for us. Sadly, though, very few people today are willing to put in the effort themselves. They hardly pray or spend normal devotional time in the Word, let alone really dig in and feast upon the Word. Many are lazy, many think it is unloving and intolerant of others ideas.
basicall, the Bible is the inspired revelation of God to us, while NONE of the creeds were as such!
Sometimes Christians almost use the Creeds to check the Bible, opposite needs to be the case!
