The absense of a baptism is not condemning, but it is rather telling. It means Obama's conversion was not an important enough event to properly ritualize nor to even remember details of.

What is Obama's true faith? I would have to say that it is a tolerant, universalist pan-Christianity that believes there are many equal paths to God.
Mathew 7:20

Should I question his salvation? No, not my place.
