This blog has its own canonization policy: every serious Christian, whom I refer to by name in the 3rd person, is a "Saint" (e.g. St. Faraday). I will try to give them this title on the first mention in any blog post; if I forget (or if I refer to someone without realizing they are a Christian) feel free to tell me!
This policy is inspired by how the word "saints" was used in the early church to refer to ordinary Christians, e.g. St. Paul addresses one of his letters to "the saints in Ephesus", meaning every person in the congregation. It emphasizes the fact that the Holy Spirit dwells inside every person who gives their life over to Jesus in order to become one of his Fathers's children.
You may ask, who am I to judge whether someone is really a Christian or not? The answer is that I am nobody, but this blog is a statement of my own personal opinions, so there. According to St. Paul, we are responsible for judging people who claim to be in the Church, but it is none of our buisness to judge people outside of it. If I do not call someone a saint, it might well still be the case that they have a holiness inside them, which I don't perceive. That is between them and God.
