I don’t particularly think it would be that beneficial.

Making it clear that some form of penance/sacrifice is required every friday, yes, I think that is a great idea and can be hugely beneficial. Abstaining from meat? I grew up doing that, and still try to do it today, but just out of respect for the tradition, is not actually a sacrifice for me at all. What is a sacrifice is not snacking, or eating smaller/plainer meals, eating burnt food or something, not eating meat just isn’t a big deal, and no, I’m not a vegetarian.So my take on it? They should avoid giving a specific action, such as abstaining from meat, as the necessary sacrifice, (although there is nothing wrong with highly suggesting it because of the great tradition of the Church throughout the ages, to be in solidarity with those Catholics who lost their lives over this practice) but instead it should be made crystal clear that it is mandatory to perform some form of sacrifice on Fridays and so to turn Friday’s into a day of penance.
