The appearance of Jesus that we know today seems to have been copied from a Merovingian king, so it also depends on whom do you think the one you have in the altar represents.
There's also the danger of ending up worshipping an egregor formed by thousands of followers throughout 2000 years instead of the real god that we now call Jesus. I don't believe in this much, but it's a possibility.
