About Us

Trinity United Reformed Church is affiliated with the United Reformed Churches in North America (URCNA). This federation was formed by believers who were concerned that a number of Reformed denominations are departing from scriptural teachings to accommodate modern social trends.

Although members of our congregation have come from various church backgrounds, we are united in our belief in the Bible and the creeds of the church. We adhere to the teachings of the Reformation: salvation by grace alone, through faith alone, through scripture alone, through Christ alone. We also believe that God works in all areas of our lives through the Holy Spirit.

Trinity United Reformed Church meets on the campus of Holy Cross Lutheran Church in Concord, California. For directions, please click here.

Beliefs and Practices

We believe that Scripture alone is the inerrant rule for the life of the believer and the Church. It teaches that salvation from sin was accomplished by the sacrificial work of Jesus alone, and that we are delivered from God's wrath by grace alone through the operation of the Holy Spirit. Justification is by grace alone through faith alone in Jesus Christ.

Trinity United Reformed Church subscribes to the three forms of unity: the Heidelberg Catechism, the Belgic Confession, and the Canons of Dort. These doctrines maintain that the Old and New Testaments are the infallible, unchanging and inspired Word of God.

Although Scripture's primary subject is the message of redemption from sin through Jesus Christ, all Scripture is God's word and is always true. God's special revelation in the Bible is compatible in every respect with His general revelation in nature. Human interpretation of general revelation must submit to the authority of His Word. When Scripture speaks to matters of history, science, ethics or anything else, it is true and authoritative.

We recognize that we worship an awesome and holy God. Our worship services are centered on Him. As such, they are planned to glorify and please God rather than to entertain man. Our sermons are based on the Bible and are intended to edify, comfort and encourage us to lead lives that are pleasing to our Lord and Savior Jesus Christ as we follow in obedience to Him. Music is an essential part of our services as we sing hymns of praise and thanks to our Savior. The music comes from a variety of traditional sources and cultures. The lyrics are centered on God rather than man.
