I have seen no manifestation in Obama of being what anyone would consider "devout". After more than a quarter century of no discernable Christianity, he took up with Wright's congregation in South Chicago. Wright is unapologetic about being a proponent of Black Liberation Theology. After considerable controversy, Obama cut his ties with Wright, but will wait until after the election to tell us where he's going to "worship" next, although it's clear he used his church as a political base and a source of African authenticity.
Meanwhile, he occasionally tosses out a little random "obscure" scripture, but nothing like a credible testimonial to the Lord.
As for never having been a Muslim, he was considered so by his African family, he was registered in the Indonesian public schools as a Muslim by his adoptive stepfather, and his teachers recall him receiving Muslim instruction. For the record, I don't hold that against him, as he was a child. I do hold lies against him. Thou shall not bear false witness.
Good post ntnychik.
