The Disbelief of the Christians; `Isa Only called to Tawhid
Allah says;
لَقَدْ كَفَرَ الَّذِينَ قَالُواْ إِنَّ اللّهَ هُوَ الْمَسِيحُ ابْنُ مَرْيَمَ
Surely, they have disbelieved who say;"Allah is the Messiah (`Isa), son of Maryam."
Allah states that the Christians such sects as Monarchite, Jacobite and Nestorite are disbelievers, those among them who say that `Isa is Allah. Allah is far holier than what they attribute to Him. They made this claim in spite of the fact that `Isa made it known that he was the servant of Allah and His Messenger.
The first words that `Isa uttered when he was still a baby in the cradle were, "I am Abdullah (the servant of Allah)." He did not say, "I am Allah," or, "I am the son of Allah." Rather, he said,
إِنِّى عَبْدُ اللَّهِ ءَاتَانِىَ الْكِتَـبَ وَجَعَلَنِى نَبِيّاً
Verily, I am a servant of Allah, He has given me the Scripture and made me a Prophet. (19;30) until he said,
وَإِنَّ اللَّهَ رَبِّى وَرَبُّكُمْ فَاعْبُدُوهُ هَـذَا صِرَطٌ مُّسْتَقِيمٌ
"And verily Allah is my Lord and your Lord. So worship Him (Alone). That is the straight path." (19;36)
He also proclaimed to them when he was a man, after he was sent as a Prophet, commanding them to worship his Lord and their Lord, alone without partners,
وَقَالَ الْمَسِيحُ يَا بَنِي إِسْرَايِيلَ اعْبُدُواْ اللّهَ رَبِّي وَرَبَّكُمْ إِنَّهُ مَن يُشْرِكْ بِاللّهِ
But the Messiah said, "O Children of Israel! worship Allah, my Lord and your Lord." Verily, whosoever sets up partners with Allah...,
in worship;
فَقَدْ حَرَّمَ اللّهُ عَلَيهِ الْجَنَّةَ وَمَأْوَاهُ النَّارُ
then Allah has forbidden Paradise for him, and the Fire will be his abode.
as He will send him to the Fire and forbid Paradise for him.
Allah also said;
إِنَّ اللَّهَ لَا يَغْفِرُ أَن يُشْرَكَ بِهِ وَيَغْفِرُ مَا دُونَ ذَلِكَ لِمَن يَشَأءُ
Verily, Allah forgives not that partners should be set up with Him (in worship), but He forgives except that (anything else) to whom He wills. (4;48)
and,
وَنَادَى أَصْحَـبُ النَّارِ أَصْحَـبَ الْجَنَّةِ أَنْ أَفِيضُواْ عَلَيْنَا مِنَ الْمَأءِ أَوْ مِمَّا رَزَقَكُمُ اللَّهُ قَالُواْ إِنَّ اللَّهَ حَرَّمَهُمَا عَلَى الْكَـفِرِينَ
And the dwellers of the Fire will call to the dwellers of Paradise; "Pour on us some water or anything that Allah has provide you with." They will say;"Allah has forbidden both to the disbelievers." (7;50)
It is recorded in the Sahih that the Prophet had someone proclaim to the people,
إِنَّ الْجَنَّةَ لَا يَدْخُلُهَا إِلاَّ نَفْسٌ مُسْلِمَة
Only a Muslim soul shall enter Paradise.
In another narration,
مُوْمِنَة
Only a believing soul...
This is why Allah said that `Isa said to the Children of Israel,
إِنَّهُ مَن يُشْرِكْ بِاللّهِ
فَقَدْ حَرَّمَ اللّهُ عَلَيهِ الْجَنَّةَ وَمَأْوَاهُ النَّارُ وَمَا لِلظَّالِمِينَ مِنْ أَنصَارٍ
Verily, whosoever sets up partners with Allah, then Allah has forbidden Paradise for him, and the Fire will be his abode. And there are no helpers for the wrongdoers.
There is no help from Allah, nor anyone who will support or protect them from the state they will be in.
