I worry about “true believers” who cannot carry any doubt or anxiety at all, as Thomas the Apostle and Mother Teresa learned to do. People who are so certain always seem like Hamlet's queen “protesting too much” and trying too hard. To hold the full mystery of life is always to endure its other half, which is the equal mystery of death and doubt. To know anything fully is always to hold that part of it which is still mysterious and unknowable.
