Hi Vic,
You claim that Martin Luther and John Calvin believed the Scripture was only referring to Jesus' brothers and sisters as "kinsmen." That may or may not be true. If so, it is not the only issue where I would disagree with these two. Yet, I would agree with both on my issues.
I know that Martin Luther did not necessarily want to leave the Roman Catholic church; but, only to change some of their teachings. One was that Luther had found that Scripture teaches that we are saved by grace through faith -- alone. This was part of his 95 Theses.
And, John Calvin and I disagree strongly on his teaching of predestination. But, yet we agree that a true believer cannot lose his/her salvation.
But, let's go back about 1500 years earlier, to the writings of Matthew and Mark -- those who walked with Jesus Christ or who had close association with those who walked with Him.
Matthew 13:55-56, "Is not this the carpenter's son? Is not His mother called Mary, and His brothers, James and Joseph and Simon and Judas? And His sisters, are they not all with us? Where then did this man get all these things?"
Mark 6:3, "Is not this the carpenter, the son of Mary, and brother of James and Joses and Judas and Simon? Are not His sisters here with us?" And they took offense at Him."
Mark 10:29 Jesus said, "Truly I say to you, there is no one who has left house or brothers or sisters or mother or father or children or farms, for My sake and for the Gospel's sake."
There can be no doubt that these were the blood relatives if Jesus Christ, children of Joseph and Mary. At many other places where the writers meant "Christian brothers and sisters" -- they used the word "brethren."
Hebrews 2:17, "Therefore, He had to be made like His brethren in all things,. . ."
Acts 1:15, "At this time Peter stood up in the midst of the brethren (a gathering of about one hundred and twenty persons was there together), . . ."
Acts 6:3, "Therefore, brethren, select from among you seven men of good re****tion. . ."
1 Corinthians 15:1, "Now I make known to you, brethren, the Gospel which I preached to you,. . ."
1 Corinthians 16:20, "All the brethren greet you. . . "
James 1:2, "Consider it all joy, my brethren, when you encounter various trials."
James 1:16, "Do not be deceived, my beloved brethren. . . "
James 1:19, "This you know, my beloved brethren. . . "
Vic, nowhere in Scripture does it support the teaching that Mary had an "immaculate birth" -- or that Mary was "sinless" -- or that Mary was "raptured, i.e., the assumption" -- or that Mary "remained a virgin." None of these are found in the Bible. Some mention may be found in the Apocrypha -- but, not in the Bible.
Vic, I am not trying to be disagreeable, but, when you post articles or statements on the forum which I know are not Biblical -- and you imply that they are Biblical -- I must refute your claim.
But, I will have to agree with the last paragraph in your post:
The question of whether Mary and Joseph had sexual relations and the implications of that question are complex, and it lead us to consider the dogma of the perpetual virginity of the Blessed Virgin. What does the dogma mean and why does it matter?
I will have to ask the same question: What does it matter if Mary had other children after she gave birth to Jesus Christ?
Mary was chosen as a virgin and kept as a virgin to fulfill Scripture:
Isaiah 7:14, "Therefore the Lord Himself will give you a sign: Behold, a virgin will be with child and bear a son, and she will call His name Immanuel."
Isaiah 9:6, "For a child will be born to us, a son will be given to us; And the government will rest on His shoulders; And His name will be called Wonderful Counselor, Mighty God, Eternal Father, Prince of Peace."
Mary had to remain a virgin until after the birth of Jesus Christ -- for He is the spotless Lamb, the Son to be born to us from God. After His birth, there was no reason Mary and Joseph could not have resumed a normal married life. And, there is nothing in the Bible to indicate that they did not.
God bless, have a wonderful, blessed day,
Bill
