   Some other considerations:
     * The amount of donated funds does not equal the total income from
       the group. What are the other sources of monies?
     * Every member of the board of the UMJC (Union of Messianic Jewish
       Congregations) is ordained and a member of a mainline Christian
       church. Most are either AOG (Assemblies of G-d) or Baptist.
