At the first annual convention in 1951 only the German language was used, but at the 1965 convention English had replaced German. Communion services in most conference churches include footwashing, however, the common cup with wine has generally been replaced with grape juice and individual cups. Another significant change from tradition was made in 1973 when the Conference Council adopted a resolution that would allow churches to practice baptism by immersion as well as the traditional pouring. While all of the older established churches continue to baptize by pouring, a few of the newer churches are also baptizing by immersion. In contrast to the 1950s, the majority of conference churches now support congregational singing with musical instruments and encourage choir and group participation.
Many churches still practise a plural ministry with the leading minister placed on salary.
Most of the younger ministers of the conference now have at least some formal theological training. This work is presently administered by a nine-member board which is elected by the Conference Council. The Missions Auxiliary, a paraconference fundraising organization, was instrumental in providing funds to construct radio station ZP-30 in west Paraguay in 1975. The Board of Education and Publication, consisting of nine members, has been responsible for promoting Christian education in the conference, as well as being the publishing agent and editorial board for all conference publications. It has also been responsible for publishing the annual E.M.C. Yearbook, which records the yearly activities and records of the conference.
