To a Christian, the divinity of the risen Christ is a matter of faith, and so not subject to critical investigation.

To the rest of us, the historicity of Jesus is not taken for granted, and can be a serious matter of study.

And there is precious little evidence concerning the existence of a historical Jesus.

Jews face a similar conundrum. There is no evidence they were ever slaves in Egypt, and archaeologists have found no evidence of a 40 year trek in the desert, a lá Exodus.

For believers, none of this matters a whit. But for nonbelievers, these are legitimate fields of study.

And none of it is meant to "attack" anything. Unless the search for truth is seen as an attack.
