Are all missions/missionaries christian?

You are correct about Mormons. They are not Christian but have missionaries everywhere. Islam is spreading all over because their missions are often at the point of a gun,

Jewishness is usually a matter of birth.

The Jewish people do not recruit, nor do Hindus or Buddhists. The Christians believe that they have a mandate to sell their religion, and Muslims give only one choice, convert or be murdered.

Some religions don't believe in doing missionary work. But most do

I think that proselytizing is unique to Christianity. However, I think that Muslims do try to convert people sometimes, though not as much. I've had a Muslim man try to convert me. It didn't go over well with me, and that is why I don't try to convert anyone to Christianity. Unless someone asks, I don't talk to them about religious things. Even Jesus, when talking to someone he had just babtized, said to the guy that if anyone asks about the source of your hope, tell them. He didn't say to go around talking to strangers who don't want to talk to them, and trying to convince them of something they don't want to be convinced of. Other religions do go to other places for the purpose of doing charitable acts. But not conversion.

No.

There are many non-christian missionaries: Mormons, Jehovah's Witnesses, Atheists, Hare Krishnas, et. al.

The only thing that makes sense is the missionary style. One of the females most favorite positions.

Simple in other religions no one want to do it. I meant dosnt ready to give their life for missionaries...

well, all the CHRISTIAN ones are.
