In addition, it is not only those Scriptures about His brothers and sisters which non-Catholics use to support their contention that Mary was not a virgin and Jesus had siblings.There's the verses in Matthew 1 ....
Verse 18 Now the birth of Jesus Christ took place in this way. When his mother Mary had been betrothed to Joseph, before they came together she was found to be with child from the Holy Spirit.
And the well known one in verse 25....
25but knew her not until she had given birth to a son. And he called his name Jesus.
Both verses clearly indicate by their plain reading and meaning, that they DID consummate their marriage after the birth of Christ.
Well, I guess, God screwed up those scriptures by implying there was a true, valid, consummated marriage.
Odd, that He would leave us with such a wrong impression for the incredibly important doctrine of perpetual virginity.
Fortunately, for us, the pagan, goddess worhip influence of 300 years after the events was able to set us straight.
If you read the scripture according to waht the Protestat charlatans teach about it, you can end up with all kinds of impressions and God is not going to help you. "Thinkest thou that thou understandest what thou readest?".
