Too Like the Lightning (Terra Ignota, #1)

by Ada Palmer

I am sure of only one thing, reader: there is Providence. There is a Plan at work behind this world, and a Mind behind that plan, Whose infinite workings I cannot hope to penetrate. I could tell you what my old self thought was the purpose of my crimes. I could tell you what I think now. But only our Creator truly understands the ends to which He turns His instruments: why He had me kill those seventeen people, not sixteen, not eighteen; why He sent Bridger this bloodstained guardian; or why He chose that night of March the twenty-fifth to reveal to His devoted priest Carlyle Foster that, in His strange Mercy, He had spared, of all men, Mycroft Canner.

So Mycroft has come to some sort of religious belief system.
