Beautiful German Architecture

Trinity Lutheran Church originated as a German-speaking Lutheran church. The Germanic heritage can be seen in the beautiful design of the church, with wood accents, cathedral ceilings lined with wooden beams, stone walls, and an exterior that resembles a castle.  The pipes of the organ accents the wall behind the altar, as wooden pews line the aisle.  Beautiful arched stained glass windows line each side of the sanctuary.

Formation of Lutheran Churches

Lutheran churches follow the Christian beliefs that are in the old and new Testaments of the Bible. We follow the teachings of Jesus Christ by sharing Christianity to others in our community and around the world. The Lutheran churches came about from the reformation of the Protestants churches in the 1500s, led by a German monk and scholar named Martin Luther. Luther's "95 Theses," held two central beliefs - that the Bible is the central religious authority and that humans may reach salvation only by their faith and not by their deeds.

Lutheran Congregations in Mission for Christ

"We're Lutheran Congregations in Mission for Christ, and our name pretty much says it all. We're not a denomination, we're a movement. We view the local church as the place where people in the community come to get connected with God and one another. We celebrate the fact that everyone is wired a little differently; it allows each and every one of us to serve according to our own unique strengths, skills and talents." -LCMC
