I have not fully read the article above, but wanted to comment regarding any idea that Epicurean philosophy would be a better option for an individual interested in Christianity -- I think that anyone who is moving toward Christianity hasn't fully dealt with certain existential questions, and that they have certain psychological desires that they want to see fulfilled. The foremost desire would be for "immortality" since within Christian belief the soul does not die. Asking anyone with that desire to consider Epicureanism would not go over well. A given person in this situation won't accept something that they aren't wanting or ready to hear.
Unfortunately modernity and the larger system what we now exist within, directly or indirectly reinforces the idea of an immortal soul. Maybe the "desire for immortality" is a chicken-and-egg thing, that feeds back into itself - present in religion and present in masses and the mythos of civilization itself.
