Let's say there's a single man, and he is morally disordered to the point where Matrimony and Orders are lifestyles that are, short of a third degree miracle, out of the question. And let's say this individual is so immature, undisciplined, and caught up in addictive sinful behavior, that he doesn't seem to be able to stay in a state of grace for more than a few hours: would it be a viable option to pursue cloistered religious life: not based upon a holy desire to sacrifice one's life to serve Christ and His Church, but based upon a desperate desire to force oneself to be placed in a strict environment that would possibly force said individual to stay just holy enough to make it to the purifying flames of Purgatory?

imo, no.

Religious life is not intended as a way to hide from the world.

Having lived in a Benedictine Abbey for a year, as a candidate and then a postulant, let me tell you: being cloistered does NOT stop you from sinning, infact because you are confronted with yourself daily and have to look at yourself very closely, chances are any sin or mental health issue will be magnified a thousand fold...We had one novice, who had had 'mild depression' when she came in, and within 2 or 3 years had much worse depression and needed outside treatment. After she recovered, she was actually advised (by our Mother Abbess and her psychiatrist) that it was not wise to pursue her vocation any further, because being confronted with herself and her issues was just too intense. Now, with sin it'll be a similar situation...if anything, you've got very little to take your mind off it in a cloistered situation, and if you do and have a certain personality you have the chance it will 'out' itself in a different area of your life. Also, God never meant for us to 'lock ourselves away from sin', He wants us to OVERCOME sin.

thank you for the feedback.
