'Did Mary magdaline really marry Jeus Christ and is there still a bloodline?

No! Jesus never married.That came from a fiction novel stupid people thought was true.He got the idea from ancient writings where it states they saw Jesus kissing her on lips indicating they were married. further investigation finds that in the original manuscript the part that shows them kissing was not in the original but added by some unknown person at a later date.they quote non-Biblical books found not inspired by God but written by some jew claiming Jesus loved her more than the others,no evidence of sex or marriage except in the imagination of former readers interperting it as they felt should be , not as it was written.God was not speaking during this period so many Jewish writers wrote books hoping to make people keep the faith.some are historical,and the rest is actually insanity by fruit-cakes.reading some would make you feel like you are in a mental hospital or the writers belonged there.A few was in the church but was horribly corrupted through the ages(Catholic Church) such as the Book of Jasher(I have it).Go by your Bible. It is very accurate & can be trusted as God-Inspired.
