Iona Community

The Iona community is known for its vibrant approach to worship, blending contemporary, poetic language with ancient practices and art. Their liturgical pieces are awesome - just great words that make you think and challenge you. Interwoven in their worship services are calls to justice, concern for creation, and love for neighbor.

I'd highly suggest checking out their resources as a way to jump start worship planning, infuse new ideas into traditional or contemporary services, and get people excited again about call/response elements of worship.
