The word(s) "christian" appears 16 time(s) in 15 verse(s) in Quran in Muhammad Pickthal translation.

(11) Lo! those who believe, and those who are Jews, and Sabaeans, and christians - Whosoever believeth in Allah and the Last Day and doeth right - there shall no fear come upon them neither shall they grieve.

(12) Thou wilt find the most vehement of mankind in hostility to those who believe (to be) the Jews and the idolaters. And thou wilt find the nearest of them in affection to those who believe (to be) those who say: Lo! We are christians. That is because there are among them priests and monks, and because they are not proud.

(13) And the Jews say: Ezra is the son of Allah, and the christians say: The Messiah is the son of Allah. That is their saying with their mouths. They imitate the saying of those who disbelieved of old. Allah (Himself) fighteth against them. How perverse are they!

(14) O ye who believe! Lo! many of the (Jewish) rabbis and the (christian) monks devour the wealth of mankind wantonly and debar (men) from the way of Allah. They who hoard up gold and silver and spend it not in the way of Allah, unto them give tidings (O Muhammad) of a painful doom,

(15) Lo! those who believe (this revelation), and those who are Jews, and the Sabaeans and the christians and the Magians and the idolaters - Lo! Allah will decide between them on the Day of Resurrection. Lo! Allah is Witness over all things.
