For a minute, I was so angry that I forgot the purpose of the questions to you. That creeds change as the word of God changes. NO WAIT THAT ISN'T CORRECT. HIS WORD NEVER CHANGES. It's MEN who change His word in order to deceive. And form new, improved creeds for all the itching ears in the audience.
I've posted this to you, so a reply would be expected. Otherwise, begone. You may accuse others of things, but you will not accuse me unjustly.
If you want to have some legitimacy and credibility you need to put in the work to actually understand Catholic doctrine and dogma before you can intelligently criticize it. I'll dumb this down as much as possible, but try to keep up.
The Nicene Creed is not a Catechism, it is a confession of Faith. Please note that it does indeed include a reference to the "Virgin Mary" as an acknowledgment of her very special role in the Salvation of mankind. Unlike some of the fringe Protestant doctrines espoused in these threads, Catholic doctrine is not defined by a single out of context citation from Paul or found in a 2 hour sermon written 2,000 year later. The Nicene Creed, in part, established the orthodoxy of Christianity and with it the Canon of Scripture. The entire revealed Word of God, which includes the Scripture and the Apostolic tradition, forms the basis of for the Assumption of Mary.
