Jesus said ’Allah’, not ’Deus.’

Jesus’ native language was Aramaic. The Aramaic translation of the gospels present Jesus praying to and praising the God Whom he worshiped, naming him AaLah or AaLoh (the ’Eastern’ and ’Western’ vocalisations). Jesus surrendered to his Lord, and his words (whether or not they are authentically preserved) indicate perfect slavehood to El/Elohim (Hebrew), AaLaH (Aramaic), Allaha (Syriac), Allah, the true name of the One God of Abraham. Say: O People of the Scripture! Come to a common word between us and you: that we shall worship none but Allah, and that we shall ascribe no partner unto Him, and that none of us shall take others for lords beside Allah. And if they turn away, then say: Bear witness that we are they who have surrendered (unto Him). Qur’an 3:64
