Fr. Daniel Poovannathil unequivocally clears confusions around the verses which can be interpreted as Jesus having other siblings from his mother Mary, by quoting other verses from bible and usage of the word "brother" in Hebrew language. He continues explaining why Jesus said "Anyone who does the will of my Father in heaven is my brother and sister and mother".
