What you are presenting here is strictly theory and conjecture. Not an OUNCE of fact is presented here. The Bible mentions that Mary was a virgin ONLY at the time of her conception of Jesus. Period. It ends there. Since Mary and Joseph were a MARRIED COUPLE and since the Bible mentions Jesus’s brothers and sisters, it is reasonable, natural, and normal to reasonably conclude that Mary and Joseph had a happy normal close marriage which was blessed with other children. Why is this soooooooooooooooooooooooooooooooooooooo difficult to believe????? To believe otherwise, you would have to conclude that Joseph was a passive wall flower and that Mary and Joseph slept in separate rooms. I don’t think that’s how Holy Matrimony works for anyone. You just offer theory not facts based on Biblical accounts which is our primary source.
God’s plan is for Holy Matrimony. His plan is for to be fruitful and multiply. He created Eve because He did not want Adam to be alone. The Church invented celibacy. That is NOT God’s plan for Mary and Joseph. That is NOT God’s plan for men and women. That is SPECIFICALLY NOT God’s plan for the clergy-—for proof of this simply read 1 Timothy 3:1-7. READ IT AGAIN. Then you tell me what that means. Holy Matrimony is God’s plan for men and women and their families. This all throughout the Bible. Only the Romans seemed to glorify virginity as goal in of itself-—remember the vestal virgins? Of course celibacy is the preferred state outside of Holy Matrimony. But marriage is God’s plan for us-—and this not to be excluded to our clergy if you read 1 Timothy 3:2.
Is the trinity written out word for word in the Bible? No. However, one can reason to it.
Is perpetual virginity written out in the Bible? No. However, one can reason to it.
However, to reason to it, one must understand several things. One would be the archtype of the new Eve. The second would be the role of virgins in ancient, specifically Jewish society. One would have to have a thorough understanding of Koine Greek. Finally, one would have to be able to synthesize all of that data.
As we look at the books of the Bible with our 21st century eyes, much of what seems clear really isn’t. However, when viewed from the lens of ancients, as well as the writings of scholars throughout the ages, such as St. Thomas Acquinas, St. Augustine, St. Polycarp (to name a few), we find that perpetual virginity has been an accepted teaching since the first century.
God didn’t want Adam to be alone, that’s right. However, Joseph wasn’t Adam, and Mary wasn’t Eve. Additionally, religious celibates were common, and were commended by Jesus Himself, “and there are those who choose to live like eunuchs for the sake of the kingdom of heaven. The one who can accept this should accept it.” (Matthew 19:12)
God wants us to be fruitful and multiply, in general. But that is not a commandment.
If you are struggling with these dogmas, it is worthwhile to speak with your pastor. I am sure he can walk you through these doubts.
