This is from HymnSite.com. I searched for hymns appropriate to All Saints' Day, and found some useful suggestions. Note, however, the themes for these particular hymns. There were several others listed for All Saints', but these are the ones that shared this theme: "the righteous live by faith/do the right thing".
The important thing about the death and resurrection of Jesus the Christ, and the holy Church he instituted through his Apostles, is the lessons we can learn. And the lesson we learn from Jesus and all the saints who have come before us, in all their passion, suffering, and martyrdom, is this:
Do The Right Thing. Doing the right thing, boys and girls, is just like living by faith. Same thing, just about.
As I meditate upon this, I realize that the perfect All Saints' hymn has been staring me in the face this whole time. We should all learn the song "Divisionary", by Ages and Ages, which urges us to "do the right thing, do it all the time", "make yourself right, never mind them" and "we know better than that to take'em serious, still don't let'em make you bitter in the process". This is wisdom and grace for the ages, Ages and Ages.
This is the gospel of Jesus, right? Do the right thing, do it all the time. So will you inherit eternal life. Sing it out.
