They drew the distinction and demonstrated that they could draw the distinction. The word kindred (suggenes) is translated "cousin."
Luke 14:12 And he said also to him who did call him, `When thou mayest make a dinner or a supper, be not calling thy friends, nor thy brethren, nor thy kindred, nor rich neighbours, lest they may also call thee again, and a recompense may come to thee; These lists demonstrate that words are being distinguished from one another. There is a distinction between a man's brothers and his "kindred, blood relatives, kinfolk, cousins." IN SHORT, the Protestant position MUST be admitted to be entirely tenable, and those who reject fellowship based on this difference are being dishonest with other Christians."
Lu 21:16 And ye shall be betrayed both by parents, and brethren, and kinsfolks, and friends; and some of you shall they cause to be put to death.
Mt 13:55 - Is this not the carpenter's son? Is not His mother called Mary? And His brothers James, Joses, Simon, and Judas?
Mt 12:46 - While He was still talking to the multitudes, behold, His mother and brothers stood outside, seeking to speak with Him.
Mt 12:49 - And He stretched out His hand toward His disciples and said, "Here are My mother and My brothers! This is a very interesting passage in that Jesus intentionally distinguishes between these "fellowship brothers" and the "brothers associated with Mary."
Mr 6:3 - Is this not the carpenter, the Son of Mary, and brother of James, Joses, Judas, and Simon? And are not His sisters here with us?" And they were offended at Him.

They are still not identified as children of Mary. They might have been Joseph's from a prior marriage. They might have been cousins whose parents died and were raised as siblings. We don't know. What we do know is that never are their parents identified. Neither James nor Jude identify themselves as a brother of the Lord.
Why was Mary entrusted to John on the Cross? This would have been highly insulting to any siblings and quite probably illegal under Mosaic law.
Of course. Primary usage of "adelphos" is "brother (of the same parents)". The point is that when a mixture of relatives is described, or when precision is not required, or when a special kinship is indicated, the same word is used. IN SHORT, the Protestant position MUST be admitted to be entirely tenable
The protestant position is indeed tenable from scripture. But so is the Catholic/Orthodox position tenable. You position, however, is not tenable from tradition.
Jesus intentionally distinguishes between these "fellowship brothers" and the "brothers associated with Mary."
He is doing the exact opposite, He intentionally equates the two.
