It states, thus: ﴿ لَقَدْ كَفَرَ الَّذِينَ قَالُوا إِنَّ اللَّهَ هُوَ الْمَسِيحُ ابْنُ مَرْيَمَ ﴾ “They are certainly faithless who say, ‘Allah is the Messiah, son of Mary’.” [^8] ﴿ لَّقَدْ كَفَرَ الَّذِينَ قَالُواْ إِنَّ اللّهَ ثَالِثُ ثَلاَثَةٍ وَمَا مِنْ إِلَـهٍ إِلاَّ إِلَـهٌ وَاحِدٌ ﴾ “They are certainly faithless who say, ‘Allah is the third [person] of a trinity,’ while there is no god except the One God.” [^9] ﴿ وَقَالَتِ النَّصَارَى الْمَسِيحُ ابْنُ اللَّهِ ذَلِكَ قَوْلُهُمْ بِأَفْوَاهِهِمْ يُضَاهِئُونَ قَوْلَ الَّذِينَ كَفَرُوا مِنْ قَبْلُ ﴾ “And the Christians say, ‘Christ is the son of Allah.’ That is an opinion that they mouth, imitating the opinions of the faithless of former times.” [^10] It can be inferred from the last verse that belief in the divinity of the Messiah ( ‘a ) and that he is the Son of God was that of the unbelievers of the past and has crept into the religion associated with him, and it is not something which the Holy Messiah ( ‘a ) has ever taught to his followers.
