As you can guess from the name of this Sunday we honor the Trinity this weekend. Since the season of Easter ended last week we no longer begin in Acts, but turn back to the Old Testament for the first reading. This week we begin in Deuteronomy, which is a second telling of the law, Moses has many speeches and today we hear one, Moses says to the people Ask throughout the ages has anything like this (escape from Egypt, God choosing a people) happen before. Moses then says that “This is why you must know and fix in your heart that the Lord is God of the heavens above and the earth below and there is no other.” Later in Deuteronomy we hear the Shema (Hear, O Israel the Lord our God, the Lord is one) which sums up this idea rather quickly. The Lord is one and there is nothing above him.
As we turn to the letter of Paul to the Romans, we shift gears and are talking about the spirit. Paul tells us those who are led by the Spirit of the Lord are children of God. So that we may all cry out “Abba Father!” The last line I think is the most important the Spirit bears witness to our spirit that we are children of God and therefore heirs like Christ if only we suffer with him so that we will be glorified with Christ. Through the Spirit we know that we have to suffer to gain the joys of the kingdom.
Finally we reach the Gospel and it’s Matthew’s commissioning of the apostles/disciples. Jesus told the disciples to meet him on a mountain in Galilee. When they got there Jesus approached and says “Go and make disciples of all nations, baptizing them in the name of the Father, the Son and the Holy Spirit.” Jesus tells the disciples to teach all people about him. This is the Trinity; Father, Son and Spirit. All to often we forget about the triune nature of God, and just focus on one aspect of the trinity. C.S. Lewis in Mere Christianity says “If you think of the Father as something ‘out there’, in front of you, and of the Son as someone standing at your side, helping you to pray, trying to turn you into another son, then you have to think of the third Person as something inside you, or behind you.” I hope that we can all recognize the trinity working in our lives this week.
