The Missionary and Ecumenical Council was formed by the Church Assembly in February, 1963, to continue and develop the work of the Overseas Council (OC) and the Council for Ecumenical Co-operation (CACEC). It met for the first time on the 3 January 1964 at Church House, Westminster, under the Chairmanship of Sir Kenneth Grubb. The purpose of the new Council was to 'continue and develop work previously carried out by the Overseas Council and the Council for Ecumenical Co-operation' and in 1967, and the functions of the Council were listed thus:

- The Missionary Societies of the Church of England
- The provinces of the Churches of the Anglican Communion; United Churches incorporating former Anglican dioceses; and other Churches working closely with some part of the Anglican Communion where matters of missionary policy or ecumenical co-operation are concerned
- The World Council of Churches
- The British Council of Churches and the Conference of British Missionary Societies
3. To assist, when invited, in the formulation of ecumenical and missionary policy and to promote and undertake such study and research to this end as may from time to time be requested by the Archbishops, the Convocations, the Church Assembly or the Executive Officer of the Anglican Communion.
4. To bring to the notice of the Archbishop of Canterbury matters in the relationship of Church of England with other Churches which merit his attention and, if requested, to recommend a course of action.
5. To care, where necessary;
- For the interests of members of the Church of England, both clerical and lay who return to the United Kingdom after serving overseas for varying periods
