I have a nephew that is dying to be a Marine (like dad) -— probably decided against it because remaining observant was too difficult.
I think he is going to do the “lone soldier” program in Israel like his cousin (also my nep). Scared because (like me) his modern Hebrew sucks.
Remaining observant is difficult but not impossible. One chaplain we had with the 101st was extra-observant and managed well. Granted he was a chaplain, but he ensured that all his flock got the support they needed.
As with us Christians, there are times in war when wartime needs overcome some sensitivities. If the enemy’s closing in, that’s no time to safely set up for Sunday communion.
