These leaders are responsible for the development of strategic initiatives and advisements, working with the Board of Ministry and the Mission Initiative Group, as well as providing administrative support to local churches. The Union's main function is to service the churches, supporting them in mission and ministry developments. The Union also accredits ministers for leadership within Union churches. The ultimate decision making body within the Union is the annual Assembly attended by delegates from each of the member churches. The Council of the Union, normally meeting twice a year, works alongside the General Director’s Team and, in consultation with the team, shapes the policy and initiatives of the Union. The Directors of the Union oversee the workings of the Union.
