All Holiness Is God’s Holiness.
All holiness is God’s holiness in us: it is holiness that is participation and, in a certain way, more than participation, because as we participate in what we can receive from God, we become a revelation of that which transcends us. Being a limited light, we reveal the Light. But we should also remember that in this life in which we are striving towards holiness, our spirituality should be defined in very objective and precise terms. When we read books on spirituality or engage in studying the subject, we see that spirituality, explicitly or implicitly, is repeatedly defined as an attitude, a state of soul, an inner condition, a type of interiority, and so on. In reality, if you look for the ultimate definition and try to discover the inner core of spirituality, you find that spirituality does not consist of the states of soul that are familiar to us, but that it is the presence and action of the Holy Spirit in us, by us, and through us in the world.
