First, that's 12.7% of the entire Bible rather than the Protestant subset of the Bible.
Second, that 12.7% is Sunday Mass only which ignores daily Mass. Including what is read each day, the entire Bible is read at Mass each year except for portions like census figures and details only relevant to the Old Testament Jewish priesthood.
Thanks for pointing out that the One, Holy, Catholic, and Apostolic Church founded by Jesus Christ Himself still holds fast to all of the Scripture Christ and the Apostles read and relied on rather than only the subset of the Scriptures Luther couldn't get away with throwing out.
R: ....that 12.7% is Sunday Mass only which ignores daily Mass. Including what is read each day, the entire Bible is read at Mass each year except for portions like census figures and details only relevant to the Old Testament Jewish priesthood.
Check the charts in the thread I linked to. The OT reading cycle repeats every two years, and in those two years, the daily mass only covers 13.5% of the Old Testament (3378 verses). The NT reading cycle repeats every three years, and in three years' time the daily mass covers 71.5% of the New Testament (5689 verses).
Now the Bible has a total of 33001 verses, and all of them are inspired; do the math, and you'll find your daily mass only covers 27.5% of the whole. Let me emphasis this next part for the lurkers: do you, as Catholics, advocate the corporate abandonment of nearly 75% of the inspired text? Catholic apologists take Martin Luther to task for having considered removing James and Revelation from the NT. Meanwhile, Catholic liturgy has been silent on the majority of the inspired text for nearly two millennia. How else can we explain answers which mistake a minority of the Bible with the whole thing?
