Some "brothers" may be Jesus' half-brothers through Joseph.

Not possible. Since Jesus was the son of God and Mary, the only way he could have half-brothers would be for God to have sons with another woman or for Mary to have other children with an earthly man. Sons of Joseph would be step brothers at best -- actually not true brothers at all -- no half or full relation.

You're right, I meant step-brothers, I was just thinking ahead of myself and not proof-reading! Thanks for pointing it out, and God bless!
