Think about what the Holy Spirit says, and let yourself be filled with awe and gratitude: Elegit nos ante mundi constitutionem — he chose us before the foundation of the world, ut essemus sancti in conspectu eius! — that we might be holy in his presence.
—To be holy isn’t easy, but it isn’t difficult either. To be holy is to be a good Christian, to resemble Christ. The more closely a person resembles Christ, the more Christian he is, the more he belongs to Christ, the holier he is.
—And what means do we have? The same means the early faithful had, when they saw Jesus directly or caught a glimpse of him in the accounts the Apostles and Evangelists gave of him.
