Trinity is a liturgical church, and we follow the liturgical calendar through out the year. This means we celebrate the seasons of Pentecost, Lent, and Advent, in addition to the festival days of Reformation, Holy Trinity, etc. This adherence to the liturgical calendar is evidenced in our worship theme and colors for the day.


Trinity offers multiple worship services on Christmas Eve. All services include Holy Communion, and conclude by singing “Silent Night” by candlelight. We also offer worship on Christmas morning.


Trinity has online Wednesday night Lenten services during the entire season of Lent, starting with Ash Wednesday. Typically these services are shorter, often with a dramatic element to them.

Holy Week

Trinity’s Holy Week celebration starts with a ecumenical gathering with 6 other downtown churches where we commemorate Jesus entering into Jerusalem on Palm Sunday. This service happens on the street in front of St. John’s Episcopal Church at 14th & Pine Street in Boulder. Trinity also observes Triduum, the 3-day celebration of Holy Week.


Easter services at Trinity begin with an Easter Sunrise service at the Boulder Reservoir at the moment of sunrise. Next, we celebrate a festive worship at Trinity. In addition, the youth of the church serve Easter Breakfast as a fundraiser to attend Rainbow Trail Confirmation Camp.


We hold Triduum services on Maundy Thursday (where the Altar is stripped, 7 p.m.), Good Friday (Tenebrae Service, 7 p.m.), and Holy Saturday Easter Vigil (7:30 p.m.)

The Three Days before Easter are the most holy days in the life of the Christian community. They consist of one worship service spread over three days (called Triduum) to remember the most important events in the life of Jesus Christ and ultimately, his followers.

Thursday is called “Maundy Thursday.” Christians remember Jesus’ washing his disciple’s feet, blessing and sharing Holy Communion (bread and wine) during the traditional Passover meal, and then being betrayed by Judas, one of his disciples, into the hands of the Roman and Jewish authorities.

On “Good Friday,” the service continues with our re-participation in the mock trial and crucifixion of Jesus. The service ends in total darkness with Jesus being laid in the tomb.

Easter begins with “Holy Saturday” Easter Vigil, the most ancient service in Christianity. It begins in darkness on Saturday night and remembers the three women coming to Jesus’ tomb just before dawn only to discover that the stone has been rolled away and that Jesus has risen. Lights come on in the worship space and the Alleluias that have been silenced for the forty days of Lent begin to ring out. The Easter celebration continues with Festive Easter Sunday morning worship.
