[Weighingin]

Trapped's observations regarding support are true. There does not seem to be any organized ways of support. Some workers will be supported by the LSM.
Some churches, either individually or with other churches, may feel to send a monthly amount to a coworker. The elders who serve locally may be self supporting. Sometimes, monetary offerings may be given to them.

Regarding Trapped's last query, my children attended a Christian school. I was riding with the assistant principal to an event. He told me he had interviewed for pastoral jobs that had been advertised.
