You will find the people with greatest animosity towards those who acknowledge are the Jews and those who set up partners; and you will find the closest in affection to those who acknowledge are those who said, "We are Nazarenes;" that is because amongst them are Priests and Monks, and they are not arrogant.

[5:82] The word Masihiy (Christian) is not used in the Quran. The Quran refers to the supporters of Jesus with the Arabic word, Nasara, literally meaning "supporters (2:62,111,113,120,135,140; 5:14,18, 51,69,82; 9:30; 22:17). When Jesus asked them who would be his supporters in the cause of God, his disciples answered, "We are supporters of God" (3:52; 61:14). It is interesting that Jesus was called Jesus the Nazarene in the Bible, from the name of the town of Nasara. The name of the town Nasara (supporters) perhaps comes from what Jesus’ disciples called themselves. Ironically, the name of the son of Mary was not Jesus either. Christianity, as the product of the Pharisee-son-of-a-Pharisee is a polytheistic religion with a fabricated name and falsely attributed to a fabricated idol (See 3:45 and 2:62). When we read this verse within context, starting from verse 5:77, it becomes clear that the Jews referred to in verse 5:82 are not all Jews, but those who are considered unappreciative of God's blessings and message.
