Teaching students about the gifts and the fruits of the Holy Spirit is what brought me into deeper appreciation of the power of the third person of the Trinity. The Spirit is like a guide, a force, so to speak. The Church is the temple and mission of the Spirit (CCC#798,#850). The Spirit encourages wisdom, understanding, knowledge, fortitude, counsel, fear of the Lord, and piety. With these gifts, disciples are more open to God's providence and may therefore be more in tune with what God desires. Additionally, I have learned that being more in tune with what God has planned can lead to the fruits of the Holy Spirit: charity, joy, peace, patience, kindness, goodness, generosity, gentleness, faithfulness, modesty, self-control, and chastity (CCC #1832).
It is no wonder that the Spirit brings unity. It is like the tie that binds human to the divine. It weaves itself through all. Understanding the Spirit more, praying to the Spirit more, really can explain how the Catholic Church is one, holy, and apostolic as we say in our creed. It is through the Spirit that we are one and through the Eucharist that we are made whole.
At Pentecost, the Holy Spirit descended upon the disciples and filled them with the fire and the gifts needed to go forth and preach the good news for Jesus' passion, death and resurrection. I pray that you experience the power of the Holy Spirit this day and every day. May you come to know the Trinity in all its grace and beauty!
