I read somewhere today about a woman who got pregnant, not from penetrative sex, but from swallowing a wad and it somehow permeated her stomach walls and into her tubes and she became pregnant. That is probably what happened to Mary, she just swallowed a load from Joseph; she gagged on it and it travelled the same route, with the same defects in her stomach walls, and thus her hymen was intact.
Its an ecumenical question
They are even mentioning it during sermons now, that they support this persons or that persons polictics, and they said we dont support any particular side but indeed name the politicians and the party in the sermon.. wankers!
