Traditional Christian congregations divide the year into two halves. The first half follows the mission of Jesus. Four Sundays of Advent prepare the way for the Lord. The twelve days of Christmas celebrate His birth. During the Epiphany season, Christians remember the works and deeds of Jesus that reveal Him as Lord and Savior. During Lent, Christians consider the reason we need a Savior. Lent concludes with Holy Week, following Jesus to the cross. Holy Week concludes with Easter Sunday, beginning seven weeks that rejoice in the resurrection of the Lord. On Pentecost Christians remember the work of the Holy Spirit. With this, the festival half of the Church Year comes to an end, and Christians begin numbering the Sundays after Pentecost, sometimes referring to this half of the Church Year as Ordinary Time.
But the First Sunday after Pentecost is not ordinary. On this Sunday, traditional Christians remember the Holy Trinity. We recall that the one God is three Persons: Father, Son, and Holy Spirit. Each of the three is a distinct Person. They love each other. They talk to each other. They do things for each other. But they are not three gods: they are one God. One God created the world. One God tells the people he made why we are created, what we are intended to do. One God will judge us for our failure to fulfill his purpose. And one God planned our rescue, a Ransom that would pay the price for our sins, cleanse us of our failures, and reconcile us to God, making us His people forever.
The Triune nature of God was communicated in ancient times. The very word for God, “Elohim,” used many times in the Hebrew Bible, is a plural noun. From creation, God speaks of Himself in the plural, saying, “Let us make man in our image.” The Triune nature of God is found in key Bible verses, including Deuteronomy 6:4: “Hear, O Israel: the Lord our God the Lord—is One!” and Numbers 6:24-26: “The Lord bless you and keep you; the Lord make his face shine upon you and be gracious to you; the Lord lift up his countenance upon you and give you peace.” Likewise, with words that Christians enjoy singing in a variety of different tunes, the angels around the throne of God praise him with the words, “Holy, holy, holy.”
God is not like us. If God were like us, he would not be worthy of our worship and praise. If God were like us, he could not rescue us from sin and evil and death. If God were like us, our lives would have no meaning and no purpose. But God is far beyond our understanding. The mystery of the Holy Trinity gives us reason to rejoice in God, reason to trust his promises of salvation, and reason to find meaning in his reality for the lives we are living today.
God is Almighty. He can do anything. People who play with words like to ask questions such as, “If God can do anything, can he create a rock to heavy even for him to lift?” Even the Bible concedes that, being Almighty, God cannot do some things. God cannot lie. Not only is God too good to lie; God is too powerful to lie. Whatever he says happens. He says, “Let there be light,” and there is light. He says, “Your sins are forgiven,” and our sins are forgiven. He says, “You belong to me forever,” and we belong to him forever.
God is eternal and unchanging. He created time and space; he is not limited by time and space. His presence fills the universe and exists in even the tiniest of spaces. His presence also fills time. God chose a name for himself, a name pronounced “Yahweh,” a name which means, “I am.” God has no past and no future; everything in the universe is in the present tense for God. Jesus Christ is the same yesterday and today and forever. His love, his mercy, and his grace never change.
Yet one of the three Persons, the Son of God, entered creation and made himself like us. He was conceived and born into the world. He experienced time and change, growing from a baby to a boy and then a man. He is like us in every way, except that he never sinned. He obeyed all his own commands, fulfilling the Law on our behalf. He also paid the price for all our sins, becoming a ransom to rescue us from death and to grant us eternal life. He established a Church based upon the words of his prophets and apostles. He gathers His people into that Church, granting faith in his promises and promising rescue and eternal life to all who believe those promises.
God the Father sent His Son, and the Father accepts as His children all those redeemed by His Son. God the Son, as Jesus as Nazareth, is a Ransom to pay for our sins and to reconcile us to His Father. God the Holy Spirit works in the Church to share the message of Jesus, granting faith to God’s people and keeping them in that faith unto everlasting life.
The Holy Trinity is a mystery beyond our understanding. On this Sunday we rejoice in a God we do not understand, confident in his unchanging love and mercy and grace. We praise him by singing, with angels and with all the saints in heaven, “Holy, holy, holy!” J.
