About Us

Trinitas Presbyterian is committed to the bold proclamation of the Gospel of Jesus Christ, and the sheer depths of the Biblical teaching on all matters. It is our conviction that lifelong believers, no less than our secular culture, are often starved of robust exposition of the Scriptures and clear articulation of Christian doctrine. In carefully attending to the Word of God, we are convinced that participants in our ministry will be smitten with the grandeur of the Father’s love for His people, the total sufficiency of Christ’s atonement to save believers, and the power of the Holy Spirit to conform us to Christ’s character. Situated firmly within the historic Reformed tradition, the focal point of our fellowship is Lord’s Day worship. Here we sing Biblical Psalms and historic Christian hymns; confess our sins; listen to the Word of God read and preached; remember our Baptism and renew our covenant with the Lord; confess our faith and catechize one another; pray the petitions of the Lord’s Prayer; partake of the Lord’s Supper; and depart with a blessing. Nevertheless, our fellowship and worship overflows in midweek small groups, Bible studies, mercy ministries, and support for local and international missions.
