Its a mortal sin to miss Mass or to neglect Holy Days. I suspect not eating meat during Fridays of Lent falls under this category as well. How do we reconcile this teaching with Scripture that speaks against the Jewish Laws on the similiar actions.
Aren't we repeating their same mistakes?
Galatians 4:9-11
But now that you have come to know God, or rather to be known by God, how is it that you turn back again to the weak and worthless elemental things, to which you desire to be enslaved all over again?
You observe days and months and seasons and years.
I fear for you, that perhaps I have labored over you in vain.
