Just to expand on the first two paragraphs of Macbeth's long post about the Divine in terms of the first game (Divine Divinity): The Divine was your character from the first game. He/She started as a "Marked One," one of 3 people to have a spark of the Divine embedded in them after a Black Ring ceremony went wrong - the Black Ring attempted to summon and then kill the Divine (in the form of an angelic-like woman) but she escaped and split herself into three parts which inhabited 3 people, including your character. After the other two Marked Ones were killed off, your character then had to receive the Divine blessing in order to fight the Demon of Lies (a facet/servant of the Lord of Chaos). The Divine blessing was a magical ceremony where members of the 7 races were gathered to bless your character and then kill him/her. You then traveled to the realm of the dead where the 7 gods transformed you into the Divine One and resurrected you. You fought and defeated the Demon of Lies but couldn't prevent him from summoning the Lord of Chaos into a little baby's body. You (the Divine One, canonized as Lucian) raised the baby as Damian (the damned one). And that's where the rest of Macbeth's post picks up.
So, yeah there are arguably a lot of Christian motifs: Divinity, angels, a trinity, death and resurrection, a being of pure evil that must be defeated. Of course you find a lot of that stuff in many other various mythologies and fantasies as well. I'm an atheist so I don't believe in anything magical or mystical but that doesn't mean it doesn't make great entertainment. Similarity does not equal allegory. The Divinity games don't come anywhere close to being preachy or sanctimonious. Hell, even in Dragon Age, where you have a much more in-your-face Jesus/Joan of Arc type story with the religion of Andraste, you get all these chances to discredit, befoul, and otherwise invalidate the religion.
