The other way was institutional union with new United and uniting churches.

This is an umbrella organisation combining all independent Protestant regional united and uniting churches in Germany.

Furthermore, the Synod opened the possibility of admitting non-Prussian United and uniting churches to the umbrella.

United and uniting churches are churches formed from the merger or other form of union of two or more different Protestant denominations.

Member churches are Congregational, Presbyterian, Reformed and united and uniting churches.

These three churches were Lutheran, Reformed Christianity, and United and uniting churches.

The Uniting Church is an example of ecumenism; it is one of a number of United and uniting churches globally.

In fact, a merger was permanently under discussion, but never materialised due to strong regional self-confidence and traditions as well as the denominational fragmentation into Lutheran, Calvinist and United and uniting churches.

Influenced by the ecumenical movement, the "scandal of separation" and local developments, a number of United and uniting churches have formed; there are also a range of mutual recognition strategies being practiced where formal union is not feasible.

Trends are visible, however, as most united and uniting churches have one or more predecessors with heritage in the Reformed tradition (either Presbyterian, Congregationalist, or both) and many are members of the World Alliance of Reformed Churches.

The Uniting Church in Australia (UCA for initials) is a uniquely Australian church, similar to other united and uniting churches which maintain a cultural identity in their own country while expressing ecumenical fellowship with other Christian denominations worldwide.

Also, modern movements such as Fundamentalist Christianity, Pietism, Evangelicalism, Pentecostalism and the Holiness movement sometimes cross denominational lines, or in some cases create new denominations out of two or more continuing groups, (as is the case for many United and uniting churches, for example).

The uniting of GKI has been positioning GKI as the only church unity in the Indonesian ecumenical family, and one of the eight churches in the Asian and one of the eighteen churches in the global ecumenical family which formed united and uniting churches.
