This group consists of:

1.  Unmarried
2.  Single mothers

The group is voluntary as opposed to the rest of the groups that are automatic in their composition.

MESSO in its constitution, is for those who are not interested in being under MEWAK, or COGYOK for their own reasons.

 It is therefore a sub-group of the larger MEWAK group. They work together and plan how they can build the church together with others.

 Being MESSO doesn't mean that one cannot get married. They do weddings like any other unmarried member when the time permits  them.
