I would say, yes, C.S. Lewis was very much a Judeo-Christian--so much so that he married Joy Davidman, an "American" of jewish descent born in the Bronx. She was a radical communist and a feminist who at one time worked in Hollywood as a scriptwriter.
He obviously believed that this Edomite jewess could be "saved" by believing in "Jesus" as is demonstrated by the Judeo epitaph he wrote for her grave:
Here the whole world (stars, water, air,
And field, and forest, as they were
Reflected in a single mind)
Like cast off clothes was left behind
In ashes, yet with hopes that she,
Re-born from holy poverty,
In lenten lands, hereafter may
Resume them on her Easter Day

"No Rothschild is English. No Baruch, Morgenthau, Cohen, Lehman, Warburg, Kuhn, Kahn, Schiff, Sieff or Solomon was ever born Anglo-Saxon. And it is for this filth that you fight. It is for this filth that you murdered your Empire. It is this filth that elects, selects, your politicians." -- Ezra Pound
