There is a type of false piety in fashion today by which the person does not seek to deepen their religious formation.
He has never studied the truths of our faith and does not even know the catechism. In the life of piety, he is a child.
He does not know why the Church recommends meditation, how to do it or what fruits to draw from it. He does not know why we must pray, frequent the sacraments, have a profound devotion to saints. Everything in him is directed by impressions, impulses and routine; he either becomes enthusiastic with devotions or dislikes them for no reason. In him there is no upright ordination of everything according to the good norms taught by the Church.
The devotee deprived of formation does not even know that the principles of supernatural life exist. He does not know the marvels that divine grace can operate in the human soul.
How can he have a life of profound and serious piety if he does not know the value of a well-made Communion? If his meditation is poor and without horizons? If he does not know how to pray? If he does not know the mysteries of our faith? If he does not know about the communion of saints, the final resurrection, the Immaculate Conception and so on?
Let us take only one example. Saint Paul wrote: “I can do everything in Him who strengthens me.” What source of energy and courage does this message convey! It preserves us from all discouragement. It incites us to the most daring and heroic spiritual enterprises. A devotee without formation does not know all that.
