If I could just add, Edwin, as an example of quote-mining in the negative sense, you highlight Catholic Answers tracts. I hear what you’re saying; however, a tract by definition, is just that: a tract. There is only so much information one can include in such a medium, before it ceases to become a tract, and morphs into something else of a longer variety. Thus, when people pick up - or click on - a tract, and end up with something a lot more dense, that, in itself, “could” be misleading and disingenuous on the part of the publisher(s). In fact, if there’s any place where these types of quotes would be acceptable, it would be a publication such as a tract - the very thing you’ve painted in the negative in the context of quote mining.
A tract should not be, it is not, the be-all-end-all; rather, it should open the door for further, more in depth study on the part of the researcher. They can then move beyond the tract format and the quotes contained therein. And I’ve never seen a Catholic, either theologian or layperson, up to this point, warn people of going too deep into Church history, outside the confines of their mined quotes, lest they find the “truth” that the Catholic Church really can’t be the Church of Christ. The Church has nothing to hide, and isn’t relegated to selective quoting; She consistently encourages all to look into all of Church history as deep as they can. That is a pretty powerful witness.
So I don’t think indicting Catholic Answers tracts really strengthens your case. But I do agree with your general premise, in certain context(s), across traditions, as I stated earlier.
Peace brother.
