There is no such thing as pure spirituality because there is no such thing as spirituality without reality. One needs a body to have a healing, water is required for holy water.
As Chesteron reminds us, the sacraments are both certain and incredible, both ideas are true and yet a paradox. The sacraments of the Church are solidly physical and wonderfully spiritual. The sacraments, as known by the Church, are ways of seeing (faith) the invisible. Any of the seven sacraments are philosophically the same as knowing the paradox of God: Spirit becoming flesh. Look at the greatest sacrament, the Eucharist, it is spirit and substance together, it is the Presence of the One who was crucified and risen, it’s healing and food and a pledge. And all these things are true we can never exhaust the meaning of the sacrament because of its divine reality.
Sacraments coming face to face with God, and face to face with ourselves. They reveal God’s face of love and mercy, and they also pull back the veils that cover our face. God comes and finds us through the sacraments.
