  • Welcome to First Parish of Chelmsford!
    We invite everyone of good will to come to worship and to our community, in the fullness of who you are across age, race, gender, ethnicity, class, religious background, sexual orientation, ableness and family. We are a Unitarian Universalist congregation. While Unitarian Universalism began in the Protestant tradition, we have grown beyond our Christian roots into a non-creedal faith, welcoming of different spiritual and theological perspectives. Join us for worship, mutual care, and in service to the common good.

    First Parish is open for in-person worship, and we also livestream our services. However, due to the COVID pandemic, there is a restriction on the number of people allowed in the sanctuary. If you wish to attend in person, please pre-register in advance online or by calling the church office: 978 256-5133 by 10 am the Friday before. More information on our current in-person worship status is available on our Sanctuary Status page.
