For over 100 years, the ECA has served the evangelical community in a unique way by providing credentials and accountability to ministers who meet the qualifications for ordination and licensing. As an interdenominational organization, the ECA provides a large umbrella for ministers to experience unity as they carry out their calling. The faces of the ECA are made up of pastors, missionaries, evangelists, chaplains, authors, parachurch leaders and many others, which make the ECA's diversity one of its greatest strengths.
