No, i know Brian was representing Jesus, but like he was saying all movie that he wasn't the messiah and i remember he talking at a spot where others were talking and some references showed that he wasn't Jesus:

Only God Can Judge Me
الله فقط يمكنه محاكمتي

I am you and you are me, if you love i love, if you suffer i suffer
أنا أنت, و أنت أنا, إذا أحببت نفسك أحببت نفسي, إذا عانيتَ عانيتُ
