This article is aimed at religious people. It's fine. Good writers know their audience and write to them. This would make a fine sermon or lecture. But you can see how the context collapse has led to lots of snark here.

My advice: read it with the understanding that it's not for you (or me), and that it offers a perspective you might not have gotten if it targeted a more general audience.

Seneca might have been writing to his boyfriend Lucilius in his famous letters, but anyone who's read them will agree they got something out of it despite not being the target audience.
