Christians Encounter Christ (CEC) is a Catholic movement within the Archdiocese of Omaha. The CEC Method is introduced on a 3-day weekend retreat. It is a combined effort of laity and clergy toward evangelization of the world in which we live by strengthened spirituality lived and shared in everyday environments. The community spirit of the weekend is continued through group and community gatherings called Avanti Cristo. Contact: This email address is being protected from spambots.
