And I said I was not tryingto put my personal beliefs upon anyone … As for the OP -they started this thread with very vague and nebulous post that only later became one of working 60-80hours week - long hike into wilderness like conditions, etc …
Initially it appeared like a fishing expedition for an excuse to miss Mass when one went campling for 3 days [an isolated weekend] or a week [7 days] or whatever [two - three weeks

What type of response would you have serious christians make -
Sure Man - if theres no Church then there’s no obligation for as many Sundays as you can plan.
My family will be going camping in a couple of weeks - for a weekend - … we will aslo be attending Mass at a Sunday evening Mass upon our Sunday return … The OP may not be able to do so … they also might not have considered that option had other posters not mentioned the same … nor your suggestion to discuss this with priest and possibly move the obligation to another day …
Which might be the reason for Forums like this to exist
