This is an interesting segment from CBS News on an Episcopalian church in downtown Washington, D.C. that has invited a Muslim congregation to use their sanctuary for worship. Does the Bible speak to interfaith dialogue?

In the New Testament it is written:
2 Corinthians 6:13–17 (KJV 1900)
Be ye not unequally yoked together with unbelievers: for what fellowship hath righteousness with unrighteousness? and what communion hath light with darkness? And what concord hath Christ with Belial? or what part hath he that believeth with an infidel?
Ye are the temple of the living God; as God hath said, I will dwell in them, and walk in them; and I will be their God, and they shall be my people. Wherefore come out from among them, and be ye separate, saith the Lord, and touch not the unclean thing; and I will receive you
A prohibition on worship with heretics or infidels was understood in the early Church.
The ancient canons call for any clergyman who prays with heretics to be suspended (Apostolic Canons XLV) and for any clergyman or layman who enters the place of worship of Jews or heretics to be deposed (if a clergyman) and excommunicated (Canon LXV). Canon XXXIII of the Synod of Laodicea also states, "One must not join in prayer with heretics or schismatics".
