Huh, funny. Those books were in the Holy Scripture Jesus Christ used (and often quoted from according to the New Testament authors). That’s not opinion or religious conviction, it is simply historical fact.
Perhaps what you consider “NON-Biblical” is simply Satanic deception...in fact I am quite sure it is.
I wouldn't say it that way, but Christ Jesus NEVER used the following books: Tobit, 2 Maccabees, Wisdom, in order to teach these false doctrines:
prayers for the dead - Tobit 12:12; 2 Maccabees 12:39-45
purgatory - Wisdom 3:1-7
intercession of saints in heaven - 2 Maccabees 15L14
intercession of angels - Tobit 12:12-15
