Yes. Ideally "spiritual" people are not concerned what other people believe in and do. If anything, they are more humbled around others and accept who they are as people regardless their traditions, who they worship, and how. They'd (how I see it) would most likely help others find their way and get to know others in their belief if they really cared about how they felt and want to help them if that particular way is appropriate. People without egos wouldn't need to care who another person believes in and most definitely wouldn't care whether other people believe what he does. Egoless person would ideally "wash everyone's feet" and won't expect faith from a person (fine print) as a payment for his services. Someone who has no ego (and no spiritual pride) will have unconditional love and save all people by his death regardless if people accept it or not.
So, given that, I do feel people who wrote about christ's life made christ have a big ego. But since humans have egos and christ is flesh, it's easier to identify with people "like us" to puff our spiritual ego than to try to identify with god without incarnation in which they feel they cannot do despite god's ability to do anything.
