[Cronos]

A person can be fallible/infallible.

A book can be errant/inerrant.

A person cannot be errant/inerrant and a book cannot be fallible/infallible.

The Bible is inerrant, without errors. That is Church belief and doctrine.

This was repeated in Vatican I

These books [of the canon] the Church holds to be sacred and canonical, not because, having been composed by human industry, they were afterwards approved by her authority; nor only because they contain revelation without error; but because, having been written under the inspiration of the Holy Ghost, they have God for their author (De Fide Catholica 2:7).

and in VII

it follows that the books of Scripture must be acknowledged as teaching solidly, faithfully, and without error that truth that God wanted put into sacred writings for the sake of salvation

This rejected any form of limited inerrancy

[daniel1212]

Then your argument here would seem to be with Mark, not with those who are broad brushed as ambivalent toward sin or as Alberto Rivera conspiratorialists.
