Hi Grenville, welcome to the forum
Always nice to see a non-muslim take interest in the Qur'an mashaAllah. And you read it even thrice mashaAllah.
Out of curiosity, if you don't mind me asking that is, how would you describe your current faith, on one hand you said: "I am a Christian" using present tense, and on the other hand you say you believe in the prophethood of Muhammed (peace be upon him) and the authenticity of the Qur'an. I geuss you're still figuring that out for yourself, which is cool, just thought I'd ask.
Anyway to answer your question. I think there are many reasons why there is distrust among followers of different religions.
*First of all, there's the religious aspect. We are warned in the Qur'an that:
Never will the Jews or the Christians be satisfied with thee unless thou follow their form of religion. Say: "The Guidance of Allah,-that is the (only) Guidance." Wert thou to follow their desires after the knowledge which hath reached thee, then wouldst thou find neither Protector nor helper against Allah. (2:120)
I still remember the first time I read that verse, I was at that time still an atheist, and I thought to myself that this was exaggerated and offensive (astagfurAllah). Although many other verses impressed me so much that I reverted to Islam a few days later, that particular verse (among with a few others) still "troubled" me for some time. Most of my family and environment is made up out of Catholics. So I was reluctant to accept that they were as malevolent as described in that verse. But now, two years later I can only admit that the verse is definitely true. Although most of my own family and friends show respect for my religion, and claim to be ok with it, they try to seize every single opportunity to get me to follow their ways. Be this knowingly or unknowingly. Of course know, that there are other verses in the Qur'an who say different things about christians, for example there is this verse saying:
Strongest among men in enmity to the believers wilt thou find the Jews and Pagans; and nearest among them in love to the believers wilt thou find those who say, "We are Christians": because amongst these are men devoted to learning and men who have renounced the world, and they are not arrogant.
And when they listen to the revelation received by the Messenger, thou wilt see their eyes overflowing with tears, for they recognize the truth: they pray: "Our Lord! we believe; write us down among the witnesses. (5:82-83)
If we put this verse next to the previously quoted one, we suddenly create a complete different view. This verse shows that not all "Christians" are alike. and that there are among them people with good characteristics. So it's not like we should consider all people of different religions as enemy's. No, we should be open and friendly to them, and invite them to our religion. And inviting people to your religion can only be done if you acquire their trust so that they listen to you. So it's not like we should avoid them and completely distrust any interaction with them, no the only thing is we should be careful for ourselves that they don't misguide us away from the righteous path.
*Secondly, there's a psychological effect. When you have a difference of opinion with someone, one is quick to judge the other party as being deluded. So we are convinced that we are right and the other is wrong
(I know that probably comes out as being arrogant, and this doesn't mean I don't respect other religions, it's just that one doesn't truly believe if they are not completely convinced that their religion is right). Now if you have that viewpoint, where "we" are right and "they" are wrong, then of course whenever "they" say something, "we" are suspicious. Is this certain? Is this something that comes from their misguided path? Is this something I can trust?
*then thirdly there is history. Unfortunately there have been many wars and incidents between Jews, Christians and Muslims. and every incident kind of made the gap between the three different religions wider to bridge. Although this last reason is illogical
(just because your grandfathers fought with his grandfathers doesn't mean you can't trust him), I fear that this is the reason that motivates the people to distrust one-another the most. In that case that would also explain why sometimes the level of distrust, and the behavior that goes along with it is for certain individuals uncalled for.
I agree with your statements. I also believe the following would help negate much of the distrust.
1. If we would agree that there is one true God, who is the God of Abraham, rather than asserting that there is only one true brand of religion.
Wouldn't that be difficult for most christians (save for the unitarians) since that goes in against the trinity?
Hope this helps, looking forward to see more of your posts.
May allah subhana wa ta'ala guide us on the straight path.
PS: I didn't answer the poll because "brothers" is ambiguous.
On one hand we are all
brothers and sisters as descendants of Adam and Eve (peace be upon them).
But the word brother is also used for the Islamic
brother-hood, which obviously is exclusively to Muslims.
