We have also the testimony of one of the greatest thinkers and Protestant philosophers, Leibnitz, for the claim that the veneration and invocation of the saints is founded in reason, on Holy Scripture, and on the tradition of the Church. He writes: "Because we justly expect great advantage by uniting our prayers with those of our brethren here on earth, I can not understand how it can be called a crime if a person invokes the intercession of a glorified soul, or an angel. If it be really idolatry or a detestable cult to invoke the saints and the angels to intercede for us with God, I do not comprehend how Basil, Gregory Nazianzen, Ambrose, and others, who were hitherto considered saints, can be absolved from idolatry or superstition. To continue in such a practice would indeed not be a small defect in the Fathers, such as is inherent in human nature--it would be an enormous public crime. For if the Church, even in those early times, was infected with such abominable errors, let any one judge for himself what the Christian faith would eventually come to. Would not Gamaliel's proposition, to judge whether Christ's religion be divine or human from its effects, result in its disfavor?" But whilst the Catholic Church practises and recommends the veneration and invocation of the saints, she does not teach us to honor and invoke them as we do God, nor to pray to them as we do to Him. She makes a great distinction. The veneration of the saints differs from the worship of God in the following: 1. We _adore_ God as our supreme Lord. We _honor_ the saints as His faithful servants and friends. 2. We _adore_ God for His own sake. We _honor_ the saints for the gifts and prerogatives with which God endowed them. Therefore there is a difference between the prayer to God and the invocation of the saints. We pray to God asking Him to help us by His omnipotence: we pray to the saints to help us by their intercession with God. Our veneration of the saints should consist, primarily, in the imitation of their virtues. It is truly profitable only when we are intent upon following their example; for only by imitating their virtues shall we share their eternal bliss in heaven. A veneration which contents itself with honoring the saints without imitating their virtues is similar to a tree that produces leaves and blossoms but bears no fruit. The saints themselves desire that we should follow their example. Each of them, so to say, exhorts us with St. Paul, "Be ye followers of me, as I also am of Christ" (_1 Cor._ iv. 16). There is no age, no sex, no station in life for which the Catholic Church has not saints, whose example teaches us to avoid sin and to observe faithfully the commandments of God and the Church at this or that age, or in this or that station. Therefore the principal object of our invocation of the saints ought to be the obtaining of their help in following their example. Thus we shall move them to come to our aid all the more readily.
