Unity and Diversity

Seventeenth Sunday after Pentecost
    In the name of the Father, and of the Son, and of the Holy Spirit.  Amen.  A buzzword these days is “diversity.”  And while people can associate the socio-political term with some level of mistrust, when it comes to diversity in the Catholic sense, we need not fear.  We don’t fear diversity, because it is also bound up with unity.  And this connection between diversity and unity bases itself in the Most Holy Trinity, who is both One God and Three Divine Persons.
    While not directly pointing to the Trinity, it intrigued me that St. Paul, in the epistle we heard today, kept going back to threes: “One Lord, one faith, one baptism,” and “Who is above all, and through all, and in all.”  Again, this is not to equate the word “Lord” with the Father, “faith” with the Son, and “baptism” with the Holy Spirit, nor any individual Person with being above, through, or in all.  But there is something providential as God inspired St. Paul to write in a way that points to the oneness and threeness of God.
    Beginning with God’s oneness, His unity, we even get a glimpse of this in the Gospel.  When asked about the greatest commandment, our Lord replies with the second half of the shema, one of the great credal expressions of Judaism: “Hear, O Israel, the Lord is God, the Lord is one.  Therefore you shall love the Lord, your God, with your whole heart, and with your whole being, and with your whole strength.”  The unity of God forms the foundation of the commandment to love God.

   The diversity, if you will, of God, started to reveal itself most clearly in the Incarnation.  We can look to the Baptism of the Lord, when the voice of the Father spoke as St. John baptized our Lord, and the Holy Spirit hovered over our Lord in the form of a dove.  Time and time again, our Lord claims authority which only God could have, especially seen in the power of forgiving sins.  And in the Gospel of John, the people almost stone Christ, which makes him ask, “‘For which of these [good works] are you trying to stone me?’”  The people reply, “‘We are not stoning you for a good work but for blasphemy.  You, a man, are making yourself God.’”  And at the great commission at the end of the Gospel according to St. Matthew, Christ commands that his disciples to baptize “‘in the name of the Father, and of the Son, and of the Holy Spirit.’”  
    Certainly, this believe in our Triune God developed over the centuries after the Ascension and sending of the Holy Spirit at Pentecost.  Indeed, the word Trinitas, Trinity, was only first coined by Tertullian, who died in the year AD 200.  Creeds would follow from Nicea, Constantinople, Ephesus, and Chalcedon that would clarify how we understood our one God as well as the Trinity of Persons.  But the kernel of the truth of our belief in who God is was present from the beginning.
    So, when it comes to the Church, which is the Mystical Body of Christ, we see both unity and diversity operating, just as unity and diversity are attributes of God.  There is one God, but the Father is not the Son, nor the Son the Holy Spirit, nor the Holy Spirit the Father.  There is one Church established by Christ, but that one Church has different expressions across the world with different gifts and charisms.  The temptation is to overemphasize unity or overemphasize diversity.  But that would be like excluding either the Three Persons in favor of one God, or excluding the oneness of God in favor of the Three Divine Persons.  But the truth is not expressed fully when one or the other is excluded.
    So for us, God calls us to profess, though one baptism, one faith in the one God.  To reflect the unity of God we hold fast to what God has truly revealed as necessary for salvation, including those statements codified by Ecumenical Councils and Popes, as well as the teaching the Magisterium.  To vary in professions of the divinity of the Son or the Holy Spirit tears away from the unity that God desires for His Church.
    On the other hand, there are diversities in practices of how we live that faith out that vary place by place.  St. Monica struggled with the fact that Romans fasted on Saturdays, while the Milanese did not.  St. Ambrose, then bishop of Milan, said that when he was in Rome he fasted on Saturdays, but when in Milan, he did not.  Liturgically, from the beginning, there rose up legitimate differences in how the followers of Christ, united in one Church, worshiped.  While most of the Roman world spoke Greek, and so Greek was likely used in many of the earliest liturgies, Latin was introduced not too long after Christianity ceased to be a persecuted religion.  Maronites, the Catholic Rite (R-I-T-E) based in Lebanon, still uses Aramaic, as it has from the beginning, the language our Lord spoke, in at least part of its liturgy.  And as the Gospel spread, the Mass came to be celebrated in various languages, though each language was often codified and does not always match the current way that same language is used (e.g., Slavonic versus Church Slavonic).
    But this variety of languages and rites resembles Pentecost, when the Holy Spirit gave the Apostles and disciples the ability to speak in different tongues so that those who had gathered in Jerusalem for the feast could understand the preaching of the Gospel.  Still, while the languages were many, the faith they professed was one.
    So, as Catholics, we can welcome diversity in a Catholic sense, because it is also connected to a unified mission and proclamation, mimicking the way that our one God is also Three Divine Persons.  In the Mystical Body of Christ, we need not all have the same task or vocation, any more than all our body parts need to be the same.  But those diverse body parts do need to work together for the proper functioning of the body, and so the diverse members of the Church need to utilize their gifts and talents in a unified way for the proclamation of the one Gospel in the one Church that our Lord founded.  May we, the diverse members of the Mystical Body of Christ, be held together for common purpose by our Triune God: Father, Son, and Holy Spirit.  Amen.
