The only reason the revelations of Mother Teresa's interior life may scandalize some American Christians is that they are completely detached from religion as a real way of life, which is to say that they are Protestants, either internally or also in name. Religion, more often than not, is about obligation, sacrifice, and duty, not about good feelings or "self-fufillment". Yes, it can seem that we are lying to ourselves sometimes, that we aren't "keeping it real" as we youngsters like to say. But sometimes the best thing to do is to shut-up and get on with God's business. And that can mean that we don't get fuzzy feelings inside, that we don't experience any material or "spiritual" gain in this life, and that we have to "keep up appearances". That's just life, in all of its manifestations. That is why our life within the Church is so important: it takes us out of ourselves and puts us into uncomfortable situations where we have to deal with the Other, either on a personal or intellectual level. And we aren't always right. And we aren't always "happy". But we trust in God and we go on. Day in and day out. Until we enter into the Kingdom of Heaven, with the help of His grace.
