The video about being baptized seems a little ... squishy? Ecumenical? Though the line about leaving behind his sins and picking up some viruses from the Thames was pretty funny.
He almost seems like he's saying baptism is an aesthetic experience as much as anything else. Which it isn't. That said, for all I know he's got a better grasp on the significance of Christian baptism than I did when I was baptized: I was 18 and it was about time.
As with any celebrity conversion ... wait and see. Kanye's fallen off the wagon again, so I hope we're about due for a celebrity to come out a genuine saint.
