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 these confessions 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, Tuesday, Thursday, and Friday at 8:05 AM and Vespers (the evening prayer office) on Wednesday at 2:30 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. Pastor Preus would be glad to speak with you if you have additional questions about our communion practice.

When is church? The Divine Service is celebrated at Trinity every Sunday at 9:00 AM, every Saturday at 5:00 PM, and throughout the year on feast days as announced. During the school year we have daily chapel services which are open to the public: Matins (the morning prayer office) Monday, Tuesday, Thursday, and Friday at 8:05 AM and Vespers (the evening prayer office) on Wednesday at 2:30 PM.

Who is your pastor? Our pastor is the Rev. John C. Preus. You can read a bit about Pastor Preus and send him a confidential message by using the pastoral contact form or visiting the Faculty & Staff Directory.

Do you offer Bible studies? Yes. Sunday Bible classes begin at 10:30 AM. The women’s study meets at 10:30 AM on Wednesdays. The men’s study meets at 6:30 AM on Tuesdays.

Do you offer a new members class? Yes, we do! If you are interested in attending or would like more information, you can email Pastor Preus or call him at (307) 222-8299. New Members classes are completely free, and an intention to join the Lutheran Church is not a pre-requisite. All are welcome: inquirers (those who are simply interested in learning more about Lutheran doctrine), catechumens (those who are preparing for baptism or confirmation in the Lutheran Church), and Lutherans who just want a refresher course. If you’re not sure which category you’re in, that’s fine! Pastor Preus would be happy to speak with you about that. For times and dates of current and upcoming classes, please visit this page.
