رِسَالَةُ يُوحَنَّا ٱلرَّسُولِ ٱلْأُولَى 5:7

فَإِنَّ ٱلَّذِينَ يَشْهَدُونَ فِي ٱلسَّمَاءِ هُمْ ثَلَاثَةٌ: ٱلْآبُ، وَٱلْكَلِمَةُ، وَٱلرُّوحُ ٱلْقُدُسُ. وَهَؤُلَاءِ ٱلثَّلَاثَةُ هُمْ وَاحِدٌ.

For there are three that bear record in heaven, the Father, the Word, and the Holy Ghost: and these three are one.
