Shaping and Celebrating Our Faith
Intentional Eucharistic Communities (IECs) are those small faith communities, rooted in the Catholic tradition, which gather to celebrate Eucharist on a regular basis. Born in the enthusiasm flowing from Vatican II for a church of the people, some IECs were instituted in parishes, some were created as alternatives to the parish, some retain close ties with the institutional church, and some function independently. All are characterized by shared responsibility for the governance and life of the community. Through sharing liturgical life and mutual support for one another, members are strengthened to live Gospel-centered lives dedicated to spiritual growth and social commitment.
