Sigh.
1. You guys TEACH that Mary NEVER had sexual intercourse with Joseph.
2. The bible states:
The wife does not have authority over her own body, but the husband does; and likewise also the husband does not have authority over his own body, but the wife does. Stop depriving one another, except by agreement for a time, so that you may devote yourselves to prayer, and come together again so that Satan will not tempt you because of your lack of self-control. . . 1 Corinthians 7:4-5
3. Thus; Mary was a SINNER!
Great argument, provided you ignore everything the GOSPELS have to say about the betrothal and marriage of Joseph and Mary.
You are intellectually dishonest. You have an ideological position, and you will twist Scripture any which way in order to score cheap points for your ideology.
There isn’t a scintilla of a reason to believe that any of the Scripture passages you have cited was intended to answer questions about Mary. You abuse these Scriptures when you pretend that they DO answer theological questions about Mary.
