The priest carries out two acts: the principal one is an action on the true Body of Christ; the secondary one affects the Mystical Body of Christ. The second act or ministry depends on the first, but the reverse is not the case.
Therefore the most important part of the priestly ministry consists in trying to get Catholics to approach the Holy Sacrifice with growing purity, humility and devotion. If a priest strives to do this, he will not be cheated, nor will he defraud the consciences of his fellow Christians.
In the Holy Mass what we do is adore: we fulfil lovingly the first duty of a creature to his Creator: You shall worship the Lord your God and Him only shall you serve. Not the cold, external adoration of a servant, but an intimate esteem and attachment that befits the tender love of a son.
In the Holy Mass we find the perfect opportunity to atone for our sins and the sins of all men, so as to be able to say with Saint Paul that we are completing in our flesh what is lacking in the sufferings of Christ. No one is an isolated individual in this world; no one can consider himself completely free from blame for the evil that is done on earth, which is the result of original sin and the sum total of many Personal sins. Let us love sacrifice; let us seek atonement. How? By uniting ourselves in the Mass to Christ, who is Priest and Victim. He is always the one who bears the tremendous weight of the infidelities of men your infidelities and mine.
