Are there religions that advise against friendships with those of another faith?

Answer 1

A branch of Christianity called the Exclusive Brethren discourages friendships outside their own church. They will not share meals with outsiders. There are several different types of Exclusive Brethren. When they mix with outsiders, it's usually while they're at work. Otherwise, they keep themselves separate. They do not send their young people to college, and in the strictest of their groups, members are not permitted to read newspapers, watch TV, or listen to the radio. They do maintain a website, though, to answer questions from outsiders.

From their website:

"The Brethren believe that separation is a vital part of our loyalty to Christ and we derive this belief from the scriptures. Separation principally occurs in matters of fellowship and includes social activities such as eating and drinking, membership of societies and entertainment. Our fellowship in such activities is reserved for Brethren."

Answer 2

Jehovah's Wittnesses use the scripture "Bad associations spoil useful habits" to out law friendships with non believers.
Hence JW's are isolated from any outside views, and tend to be blinded.

Answer 3

Actually some christian sects DO NOT hinder friendship between different religion. Although they hinder the marriage of different religions

Answer 4

Islam Islam Islam, bla bla bla... they love to say Islam when it comes to bad things, and they bring false evidences and twisted translations of the quran.
OK, just look online to see what P.Muhammad did to keep good friendship with Jews Christians and infidels

Answer 5

Yes

Answer 6

2 John 1
9. Whosoever transgresseth, and abideth not in the doctrine of Christ, hath not God. He that abideth in the doctrine of Christ, he hath both the Father and the Son.
10. If there come any unto you, and bring not this doctrine, receive him not into your house, neither bid him God speed:
11. For he that biddeth him God speed is partaker of his evil deeds.

Answer 7

Islam certainly does. It goes beyond that and tells muslims to do very bad things to infidels.
Yet, I had many muslim friends while living in the United Arab Emirates and they knew full well that I was an atheist. Just as well that I wasn't living in S/Arabia!

Answer 8

The only one I know of is Islam. Here is some scripture from the Koran to prove my point.
From Surah III The Family of Imran verse 118
"O you who believe! do not take for intimate friends from among others than your own people; they do not fall short of inflicting loss upon you; they love what distresses you; vehement hatred has already appeared from out of their mouths, and what their breasts conceal is greater still; indeed, We have made the communications clear to you, if you will understand."
Surah III The Family of Imran verse 28
"Let not the believers take the unbelievers for friends rather than believers; and whoever does this, he shall have nothing of (the guardianship of) Allah, but you should guard yourselves against them, guarding carefully; and Allah makes you cautious of (retribution from) Himself; and to Allah is the eventual coming."
I think this is proof enough for Islam.

Answer 9

Most do - except for purposes of conversion. Nearly all advise to stay away from "lost causes" like myself.

Answer 10

There is no Religion (now atleast) that discourages interfaith friendships.
cypher thats a really ignorant thing to say.
