A little late on this thread, but just to comment:
In the military, we were evaluated as to our “bearing”, how we stood, how conducted ourselves, how clean our uniforms, how pressed. “Bearing” was also considered in civilian wear.
Is he a priest in his bearing? Some priests could wear gunny sacks, and you’d still KNOW they are priests. Others could run around in full vestments, not just cassocks or clerics, and people would be convinced they missed Halloween, because here are some guys in costume as priests.
Please do not insist priests wear clerics when at golf. I don’t want ambulance after ambulance heading out to the course when the sun stroke hits priests, sweltering in black shirts. We have enough of a priest shortage without that!
And no black polo shirts, either.
When priests are assisting in certain parish functions in order to set a good example of humble service, such as the night at the local homeless shelter’s kitchen or working alongside their brother KCs fixing the working poors’ cars, they should be able to wear something they can get grubby. Having been in the Navy and having worn a uniform very similar to clerics (winter working blue, which is really black, long-sleeved, and attracts heat and dirt), I can attest that clerics have no place in the kitchen or under the lift. No, an apron will not do. The dirt and grime will get around the apron.
When priests go on vacation, and that means VACATION not change of venue, they should be able to dress apropriately, but choose to avoid clerics. How will get they get any rest on vacation when every sinner in the place/ on the ship/ at the resort suddenly feels the need to confess/ get counseling/ etc.? A retreat house or monastery is NOT a vacation, and does not fall under the clerics ban.
If a priest is out running or at the gym, maybe somebody can market clerical sweats.
