**That’s the answer I expected. Your tradition certainly does contradict Scripture. Haven’t you read the Scriptures that say Mary and Josep had sex? Haven’t you read the Scriptures that say Jesus had brothers and sisters?
That takes a lot of “filling the gaps” as you said.**
Are you even capable of seeing objective truth or are you too far gone with all this anti-Catholic brainwashing to be your own man and think for yourself?
Scripture does not anywhere say that Mary and Joseph had sex.
As for the matter of Jesus having brothers and sisters I suppose next you will want us to believe you are a long lost brother (or is it sister)?
The learned Church has resolved that the brethren were “cousins”.
The terms brother and sister were used synonymously for cousins as well as for those related through tight social relationships that do not necessarily mean they where direct biological brothers and sisters. The only explicit reference to brothers pertains to: James, Joseph, or Joses, Simon, and Jude.
I suppose now you would also have us believe that the disciple John suddenly became a biological “brother” of Jesus when He spoke from the cross: " woman behold your son"? Please stop the torturous stretches of logic.
Is not His solicitude for her in His dying hour a sign that she would be left with no one whose duty it would be to care for her? And why recommend her to an outsider if she had other sons? Since there was no estrangement between Him and His “brethren”, or between them and Mary, no plausible argument is confirmed by the words with which he recommends her: ide ho uios sou, with the article before uios (son); had there been others sons, ide uios sou, without the article, would have been the proper expression.
The decisive proof, however, is that the father and mother of at least two of these “brethren” are known to us. James and Joseph, or Joses, are, as we have seen, the sons of Alpheus, or Clopas, and of Mary, the sister of Mary the Mother of Jesus, and all agree that if these are not brothers of the Saviour, the others are not. This last argument disposes also of the theory that the “brethren” of the Lord were the sons of St. Joseph by a former marriage (The Orthodox believe Joseph was a widower with sons from a prior marriage).
Other support for Church Teaching is:
It is highly significant that throughout the New Testament Mary appears as the Mother of Jesus and of Jesus alone. This is the more remarkable as she is repeatedly mentioned in connexion with her supposed sons, and, in some cases at least, it would have been quite natural to call them her sons (cf. Matthew 12:46; Mark 3:31; Luke 8:19; Acts 1:14). Again, Mary’s annual pilgrimage to Jerusalem (Luke 2:41) is quite incredible, except on the supposition that she bore no other children besides Jesus. Is it likely that she could have made the journey regularly, at a time when the burden of child-bearing and the care of an increasing number of small children (she would be the mother of at least four other sons and of several daughters, cf Matthew 13:56) would be pressing heavily upon her?
