It wouldn’t be a substitution but if I were you, knowing the medical reason, I would turn on EWTN and watch the Easter Mass from Rome. That way you get to experience a Catholic service visually.
The thing is, going to say the local “Bible” church isn’t going to do you much spiritual good.
First, you would be ‘comparing’ the services. You’d be ‘missing’ the Catholic service and you’d be disappointed with the other service.
Second, you’d have to be on constant guard not to be absorbing ‘wrong’ doctrine.
Third, you’d feel an ‘obligation’ when/if you met the nice people who would be all welcoming you at this protestant service. . .and you’d feel resentful for being obliged. And if you told these people, "Hey, I’m only here because I can’t go medically to a Catholic service’. . .don’t you think they might be, just a bit, ‘insulted?’
Like, "Oh our services aren’t good enough for you except when you just can’t physically attend a Catholic one, then suddenly you’ll grace us with your presence even though you don’t agree with our doctrines that day only as a ‘it’s better than nothing?’
