No, it's more from the perspective of what the author envisions Socrates would handle Christianity. The author is a Catholic philosopher who has studied Socrates for decades.
The concept of the book (it's more of a script actually), is Socrates mysteriously waking up in Harvard Divinity School in the 1980s and discussing theology with the other students and professors. Because they aren't rational, they just can't accept Christianity, whereas because Socrates IS rational, he reasons his way into the Christian faith.
Peter Kreeft who wrote it originally wanted to write about Socrates literally meeting Jesus, but he couldn't do it because he couldn't figure out how to write fiction about Jesus. So he figured it would be a good idea to write about Socrates indirectly meeting Jesus through reason instead.
