"Helvidius displayed excessive ignorance in concluding that Mary must have had many sons, because Christ's 'brothers' are sometimes mentioned. . . .Under the word 'brethren' the Hebrews include all cousins and other relations, whatever may be the degree of affinity." --John Calvin, commentaries on Mt. 13:55 and Jn. 7:3."
The literal meaning of the word translated brothers in Matt 13 is "of the same womb." There is another word for cousin. Were Peter and Andrew cousinsJ Were James and John cousins? And what do you with the word "sister" in Matther 13:56? Were these girls also cousins? Where in the Bible do you find the word "sister" translated as cousin? When your "church fathers" or any others for that matter clearly contradict scripture with their tradition they are teaching error. I don't how much esteem you give them.
We discussed it once on the same thread (252, 263). Now you foist your ignorance on another poster.
