Let's assume Catholics are wrong about Good Friday but if we take one of days to do that just for Jesus Christ that did so much favour for us, it worth it
In my opinion, nothing is worth it if it is wrong. Logically we should turn away from the doctrines of men.
Mark 7:7-8 King James Version (KJV)
7 Howbeit in vain do they worship me, teaching for doctrines the commandments of men.
8 For laying aside the commandment of God, ye hold the tradition of men, as the washing of pots and cups: and many other such like things ye do.
