Not at all. As Chesterton himself remarked in this Fourth Word, Christ takes upon Himself the cry of Job, all human suffering. The “bad” thief succumbs to suffering by separating himself from Christ, the “good” thief trusts in the Divinity of Christ and escorts Christ to paradise. This is what Sheen is getting at. Atheists use the mystery of human suffering to deny God. Chesterton once said, at this moment Christ becomes the “atheist” (he takes up the cry of the atheist) but does not lose his faith in Father. Hence “Into Thy Hands I commend My Spirit.”
Only a very superficial reading of Sheen’s commentary would make this “shallow.” The kind of shallow thinking is what you’d get in your run-of-the mill street corner foursquare church pastor, or televangelists in the vein of Joel Osteen and company.
Fine. If you consider that deep theological insight, you are welcome to your opinion. I just don’t share it with you.
As far as the comparisons you thoughtfully inserted at the end of your response - no doubt in the interest of civility and reasoned discussion - I’ll give them the thought they merit ... uh, done.
