I have combined the three verses because we are in front of the issue of Christianity, and these verses highlight the belief of Muslims with regard to the Prophet Issa (Jesus) (PBUH). And in order to make the matter clear to all people, we must not separate the meaning of verses of the Holy Qur’an. Allah (swt) gives us the rule that should be behavioral with regard to Christian brothers. There is a difference in doctrine between Muslims and Christians, and this difference is mentioned in these three verses. We must first discuss the doctrinal issue with thought and reason, not with strife, enmities, or the negative impact on the difference between the Islamic religion and the Christian religion.

We begin with the issue of Takfir: It is the most dangerous issue that has plagued Muslims since the era of the Kharijites, when they stood in the face of the Companions and accused the greatest of the companions to be infidels, who is Imam Ali (may Allah honour his face). All takfiri movements relied on the principle that the word (Takfir) is equivalent to killing, and these we call them takfiris: That is, they transformed the ideological doctrinal issue into a behavioral issue by committing  crimes, claiming that our religion is a religion of Takfir and they attribute to the religion what the enemies of the religion wanted, and they punish people for the doctrinal issue as if they were commissioners by Allah (swt), while ignoring the words of Allah (swt):

 لَا إِكْرَاهَ فِي الدِّينِ

(There shall be no compulsion in [acceptance of] the religion.) (Al-Baqara: 256)

 فَذَكِّرْ إِنَّمَا أَنتَ مُذَكِّرٌ (21) لَّسْتَ عَلَيْهِم بِمُصَيْطِرٍ (22)

(So remind, [O Muhammad]; you are only a reminder. (22) You are not over them a controller.) (Al-Ghashiya: 21-22)

Hence, we are not allowed to judge the non-Muslims which is the right of Allah (swt) only. So they change the Islamic rulings, for Allah (swt) has not allowed the Muslims to fight the unbelievers unless they are aggressors, Allah (swt) says:

 أُذِنَ لِلَّذِينَ يُقَاتَلُونَ بِأَنَّهُمْ ظُلِمُوا ۚ وَإِنَّ اللَّهَ عَلَىٰ نَصْرِهِمْ لَقَدِيرٌ

(Permission [to fight] has been given to those who are being fought, because they were wronged. And indeed, Allah is competent to give them victory.) (Al-Hajj: 39)

All the noble verses make it clear that Allah (swt) does not love aggressors, and clarify the sanctity of the human soul. The People of the Scripture are divided into two parts: Jews and Christians, and the Holy Quran put the basis for dealing with both of them by saying:

}  لَتَجِدَنَّ أَشَدَّ النَّاسِ عَدَاوَةً لِّلَّذِينَ آمَنُوا الْيَهُودَ وَالَّذِينَ أَشْرَكُوا ۖ وَلَتَجِدَنَّ أَقْرَبَهُم مَّوَدَّةً لِّلَّذِينَ آمَنُوا الَّذِينَ قَالُوا إِنَّا نَصَارَىٰ ۚ ذَٰلِكَ بِأَنَّ مِنْهُمْ قِسِّيسِينَ وَرُهْبَانًا وَأَنَّهُمْ لَا يَسْتَكْبِرُونَ{

(You will surely find the most intense of the people in animosity toward the believers [to be] the Jews and those who associate others with Allah; and you will find the nearest of them in affection to the believers those who say, “We are Christians.” That is because among them are priests and monks and because they are not arrogant) (Al-Maida: 82)

The Jews are mentioned before those who associate others with Allah (swt) because they are more in animosity.
