The Rev. John C. Preus was installed as pastor of Trinity Lutheran Church at the evening divine service on Saturday, June 1, at 5:00 PM. Pastor Preus’s father, the Rev. Rolf Preus, preached for the installation. Two of Pastor Preus’s brothers and a good number of brother pastors were in attendance as well as a great many visitors from the Wyoming District and beyond. What a joyous occasion! We are exceedingly grateful to have a permanent pastor. Once again, thanks are due to all of the local LCMS clergy who served us during the vacancy, especially Pastor Marcus Baikie. Soli Deo Gloria!

What do you believe? As a Lutheran congregation Trinity finds her identity in the proclamation of the catholic Christian faith: Christ died for our sins in accordance with the Scriptures and was raised to life for our justification. We believe that the prophetic and apostolic Scriptures (i.e. the Old and New Testaments) are the very Word of God written, divinely inspired and inerrant, and that they are the norm for Christian doctrine (2 Timothy 3:16-17). Our pastor and congregation have publicly subscribed to the Lutheran Confessions (i.e. the Book of Concord) because they are in complete agreement with the Scriptures and thus express “the faith which was once for all delivered to the saints” (Jude 1:3). In accordance with this one faith, the Word of God is preached in its truth and purity at Trinity and the sacraments are rightly administered. For a summary of what we as Lutherans believe, please consult the Small Catechism of Dr. Martin Luther.

What is your worship practice? We joyfully retain the Lutheran liturgy at Trinity. The Divine Service and hymns are taken straight from the Lutheran Service Book (2006) with some supplementation from The Lutheran Hymnal (1941). The Lord’s Supper is celebrated every Sunday. Our school has daily chapel services which are open to the public: Matins (the morning prayer office) Monday through Wednesday at 8:05 AM and Vespers (the evening prayer office) on Thursday at 2:45 PM.

Do you practice closed communion? Yes. In accordance with Scripture, Trinity practices closed communion (cf. “An Explanation of Closed Communion”). Visitors who are not members of congregations in fellowship with Trinity are welcome to remain in the pew during the distribution of the Sacrament or come forward for a blessing with arms folded across the chest. The pastor would be glad to speak with you if you have additional questions about our communion practice.
