Welcome to Watertown Evangelical Church

We are a group of individuals who believe in God as He has been revealed in the Bible. We strive to serve God both in our personal relationships with Him and as a community.

We are an independent, non-denominational church that welcomes people of all backgrounds. We believe that the Bible is the Word of God, and that those who worship Him must worship in Spirit and in Truth (John 4:23). Our Sunday Morning Worship Service features solid Bible teaching and contemporary music which incorporates some of the great hymns of our faith.

We welcome people of all backgrounds and invite you to join us this Sunday for worship.

Summer Sermon Series - Questions Every Christian Needs Answered


How can we engage with those who seem to have different mindset of skepticism and pluralism? How can we talk about sin, evil, judgment and absolute truth in an era of political correctness? These are the challenges Christians face today. Join us in our new sermon series – Questions Every Christians Need Answered. They are questions you don’t want to miss; questions you’d want to be aware of and be prepared to respond as we continue to engage our culture for Christ.
