Can We Believe and Trust

There has been a reaction by the different Christian establishments around the world to the Muslin outreach.

"This is [a] substantial letter which speaks of the unity of God from a Muslim perspective," he said. "It demands a substantial response which approaches the same theme from a Christian perspective."

Unfortunately there is a lot of ground to cover and trust is a big issue.

In their letter, the Islamic scholars acknowledged differences between Muslim and Christian views on Jesus. Citing verse 4:171 of the Koran, they said Muslims recognize Jesus as "a Messenger from God." (They did not quote the entire verse, however, which goes on to say "Allah is only one Allah; far be it from His glory that He should have a son." Also missing was 9:30, which reads in part, "the Christians say: The Messiah is the son of Allah ... may Allah destroy them.")

There is an aspect of Islam that makes trust difficult. (Via The Big Picture)
The Politically Incorrect Guide to Islam (and the Crusades), page 79:

When it comes to unbelievers -- particularly those who are at war with Muslims -- Muhammad enunciated quite a different principle: "War is deceit."

Specifically, he taught that lying was permissible in battle

There is suppose to be no lying but only if both parties are Muslim. There is also the concept of a truce only lasting ten years. If this is a truce between Muslims and Christians, then we as Non-Muslims should only expect it to last for 10 years as they re-arm them selves and can attack from a position of greater strength. There is sound reason that Christian leaders are hesitant to embrace the letter. It is a thin line to walk, there desire for peace and guarding oneself against attack.

Followup:

Muslims in general believe that Christians are being mislead with the deity of Christ and that if we finally except that we are mistaken about the idea of the Trinity, then all can be forgiven. When the twelfth Imam returns, Jesus Christ will also be there to enlighten the Christians to there mistake.
