I'll make you a deal -- post the ***ENTIRE*** Catholic Mass showing how "little" the Mass is based on Scripture, and I'll respond, showing otherwise. Deal?
Hang around a few hours and daniel1212 will probably post his research showing how small a percent of the Bible is read or taught in a year of mass attendance.
And that is the claim here. Much of the mass is repeated every time at the expense of exposing Romans to the rest of scripture.
