I am willing to consider 1 Maccabees canonical if those High traditions concede the very point of 1 Maccabees: the complete destruction of Hellenization, which would mean, among other things, the removal of the LXX, and the eliminating of overly-allegorical hermeneutics (Paul used it for illustration, not doctrine, and certainly not the negation of the “earthiness” of the Old Testament, which is precisely how it was employed; and this also applies to some Reformed folks today. Typology only works if your audience already agrees with you on type and anti-type).
I really can’t consider 2 Macc. as canonical. It’s okay as far as literature goes, but there are some problems (like sacrificing for dead idolaters). 3rd Macc is one of the worst books in human history.
