Trinity Sunday Prayer

  We praise Thee, O God, for having made known to us the great mystery of the Holy Trinity. Thou has granted the privilege of worshiping Thee as Father, Son, and Holy Ghost, three divine Persons in one unchanging God.

    We worship Thee, O God the Father. Thou hast created us and given us the gift of life. Thou hast sustained us through the years with the gifts of Thy love.  Thou has protected us in danger and guided us safely to this day.  For all these gifts we praise and thank Thy holy name.

We worship Thee, O God the Son. Thou wast slain and hast redeemed us to God by Thy blood. Thou hast hidden our sins with the robe of Thy righteousness. Thou hast covered our unworthiness with Thy merit.  Thou didst become the Son of Man that we might become the children of God.  For all these gifts we praise and thank Thy Holy name.

     We worship Thee, O God the Holy Ghost. Thou hast given us the gift of faith so that we know Jesus Christ as our Savior from sin and death and hell. Thou hast given us the assurance of the forgiveness of our sins through Him. Thou hast cheered us with the hope of heaven in Christ. For all these gifts we praise and thank Thy holy name.

     O Holy Trinity, preserve us always in body and soul until we stand at the last in joyful awe and wonder before Thy throne to praise Thee in the fullness of joy, world without and. Amen.

Sermon Excerpt:

I Believe
2 Corinthians 13:11-13
by Rev. Randy Quinn

Im going to break one of the first rules I learned about public speaking: Im going to begin with an apology.

Today is Trinity Sunday. There are only a couple of days in the church calendar set aside for doctrinal issues, and this is one of them. Its a day set aside to discuss and explore what it means to worship a three-in-one, one-in-three God.

While the doctrine of the Trinity is alluded to in scripture, it is never addressed directly. Rather, there are Biblical stories that raise questions, questions the church found could best be answered with the concept of the Trinity. It answers a question, however, that Im afraid were no longer asking.

And just so you know even though today is Trinity Sunday I am not obligated to speak about it. As I told the people who attend our Tuesday night Bible Study, I could easily preach without addressing the Trinity in my sermon.

So my apology is that I am choosing to speak about it anyway; knowing that the Trinity is a doctrine of theology that few, if any of us, are wondering about. But it is a core belief of the Christian faith, something that makes us unique among the worlds religions, and I believe it should be discussed openly at least once in a while. So I decided to launch into it today, even if it isnt the most pressing issue on your minds or mine, for that matter! (And I do so, knowing that my weakest area of study in seminary and my least enjoyable reading has always been in the field of theology.)

Finally, brothers and sisters, farewell. Put things in order, listen to my appeal, agree with one another, live in peace; and the God of love and peace will be with you. Greet one another with a holy kiss. All the saints greet you. The grace of the Lord Jesus Christ, the love of God, and the communion of the Holy Spirit be with all of you.
2 Cor. 13:11-13

Let me pose a question to begin, a question to ponder, one you may not have thought to ask and may not care what the answer might be: What does it mean to believe in the Trinity? What does it mean to believe in the Trinity?
