There are very many exercises, methods and acts of piety: morning and evening prayers, grace before and after meals, visits to the Blessed Sacrament, prayer of the Rosary, Way of the Cross, meditations, etc. All these are good, all these are praiseworthy, but let us never forget that the best act of piety, the most excellent and the most salutary, is the act instituted by Christ Himself, the act of which He has said: Do this in remembrance of Me... viz., the Holy Mass with subsequent Communion.
An excellent way of hearing Mass and highly to be recommended, is to follow the priest in the prayers and ceremonies which he performs at the altar.
The late Pope Pius X has put it in these few words: "Don't pray at Holy Mass, but pray the Holy Mass." Explaining himself further, His Holiness set forth: "The Holy Mass is a prayer itself, even the highest prayer that exists. It is the Sacrifice, dedicated by our Redeemer at the Cross, and repeated every day on the altar. If You wish to hear Mass as it should be heard, you must follow with eye, heart and mouth all that happens at the altar. Further, you must pray with the priest the holy words said by him in the Name of Christ and which Christ says by him. You have to associate your heart with the holy feelings which are contained in these words and in this manner you ought to follow all that happens at the altar. When acting in this way you have prayed Holy Mass."
Try to be present in church some moments before the beginning of the Holy Mass, to prepare yourself for the sublime Sacrifice of the altar. Then pray:
Eternal Father, I unite myself with the intentions and affections of our Lady of Sorrows on Calvary, and I offer Thee the Sacrifice which Thy beloved Son Jesus made of Himself on the Cross and which He now renews on this holy altar: 1. To adore Thee and give Thee the honor which is due to Thee, confessing Thy supreme dominion over all things, and the absolute dependence of everything upon Thee, who art our one and last End. 2. To thank Thee for innumerable benefits received. 3. To appease Thy justice, aroused against us by so many sins, and to make satisfaction for them. 4. To implore grace and mercy for myself, for..., for all afflicted and sorrowing, for poor sinners, for all the world, and for the holy souls in Purgatory.
