“For just as the body is one and has many members, and all the members of the body, though many, are one body, so it is with Christ. For in one Spirit we were all baptized into one body- Jews or Greeks, slaves or free- and all were made to drink of one spirit. (1 Cor. 12:12-13)” This passage from Saint Paul illustrates the fundamental and beautiful unity of Christians which the Church calls the communion of saints. According to the Catechism of the Catholic Church, “the Communion of Saints is the Church [herself]” (CCC 946), encompassing the faithful on earth, the souls in purgatory, and the saints in heaven. Through this communion, all are joined into one mystical body, sharing in Christ’s life and the spiritual goods of the Church.

As the Church is governed by one and the same Spirit, all the goods she has received are shared through unity in Christ. This communion is realized in two crucial dimensions: sancta (the sharing of holy things) and sancti (the sharing in holy persons). The peak of sancta is the Eucharist as it physically joins men to Christ and by extension the mystical body of Christ. On the other hand, sancti, the communion of holy persons, joins all baptized Christians and souls in purgatory and heaven. The communion of saints extends beyond earthly life. In fact, it unites all baptized Christians including the triumphant, who are the saints in heaven sharing in the beatific vision with God, the militant, all on earth who are baptized, and the suffering, souls bound in purgatory being cleansed of the temporal punishment for their sins. Since all the faithful form one mystical body in Christ, the good of each is communicated to the others. Like a physical body, if one suffers, all suffer and if one bears fruit all bear fruit. Thus, our goal as part of the communion of saints should be to strive to help one another.

How exactly are we called to aid one another? As members of the church militant, Catholics are called to participate in the sacrifice of the mass and receive the Eucharist to be joined with Christ. This strengthens the soul not only for spiritual warfare but to aid one another. Additionally, men must strive to live in the state of grace and are encouraged to pray suffrage for the dead. The Catechism of the Catholic Church commends men “to almsgiving indulgences and penances for the dead” (CCC 1032) In heaven, the saints pray to God both for us and for the souls in purgatory, while we on our part give honor to the saints and are encouraged to relieve the souls by applying indulgences, loosing the souls in purgatory of their temporal punishment. Ultimately, through these actions Catholics can effectively help one another on our journey to heaven. 

One modern example within this century that exemplified our duty as the militant was recently canonized Saint Carlo Acutis. Born in London, he lived a tragically short life but wasted no time not serving God. Frequently, he received the Eucharist saying that “the Eucharist was his highway to heaven.” This made him spiritually strong, but he did not stop there. He aided the poor, often giving food in his own Tupperware dishes and his own sleeping bag to the homeless. He proclaimed that the Eucharist was the highway to heaven. He even expressed concern for the horrors of hell. Thus, he would pray often for the dead. He is an excellent example of our duties as Catholics to the communion of saints. Through his work with the poor and prayers for the dead he showed a crucial example of our role on earth.

In conclusion, the Catechism of the Catholic Church defines the Communion of Saints as the Church united through the body of Christ for eternity. Though some saints are canonized we are all called to be saints. Carlo, with his exemplary life, gave an example, using the power of the Eucharist to transform lives. We, as baptized Christians, are also called to follow in his footsteps. It is most crucial to realize that these saints are our spiritual companions and soul mates helping us to get to heaven, and if we cooperate with God, we also will become saints. Ultimately, it is this universal calling to sainthood that truly unites the communion of saints. After all, our goal is also to enter the communion of saints and paradise with the Creator.
