"Protestant: you need and don't have Certainty about the Canon - but Catholicism can provide it!" 

Thanks! That's something I gleaned from a friend named Edwin. :)

Thanks for asking! It's been on pause for a while. I'm currently doing some PhD classes. Once I get to the dissertation portion I'll begin work on it once more as it's on the same subject.

@@taylorbarrett384 That's great to hear. There are very few catholic apologists willing to discuss Justification without straw-manning or without nuancing certain points. I hope you finish your book soon!

On what basis do you decide whether you accept something as scripture?

@@nathanmcdougall4624 well Tobit 12:9 contradicts scripture. Very obvious

James 2:24, "Ye see then how that by works a man is justified, and not by faith only." Romans 3:28, "Therefore we conclude that a man is justified by faith without the deeds of the law." In history some people have concluded, on the basis of the above passages (and others), that the book of James contradicts scripture, even obviously so. I don't believe it does, but I also think it's possible for well-meaning people to conclude that there is a contradiction there. How do you know that you're not in a similar situation in relation to the book of Tobit?

@@Wgaither1 If Scripture can say that some Christians can be saved through childbearing (1 Timothy 2:15) and you Protestants somehow reconcile this with Sola Fide, then you should have no problem reconciling Tobit 12:9's statement that we can be saved through almsgiving with Sola Fide.

I understand why you have difficulty with the text given the biblical teaching regarding merit and works, but while the Bible in some places teaches that salvation cannot be earned by good works, in other places it teaches that it can be. I mean, that passage in Tobit sounds like one of the parables of our Lord, in which people are saved by doing good. "Welcome to my kingdom, for when I was naked you clothed me." One way to interpret these passages about being saved by good works is to say they all are talking about works as evidence of salvation, but I find this to be a stretch. It seems more genuine to the full orb of biblical teachings to speak of a dialectic between the two ways of speaking of salvation: by works, and not by works. Both are biblical ways of speaking, even though on the surface they seem contradictory, they both have their own sense in which they are true.
