Says who?
You made some interesting, and controversial, arguments. Your blanket statements condemning Moses appointing men to share the workload, stating that Moses was wrong and that he never sought the Lord's guidance in that (implying that large churches are bad because the pastor doesn't recall the names of every attendee by sight) - yet you provided not a single scripture reference to support your arguments. Do you have any, or are you just speculating based upon your own rationale/human reason?
It is you is only using human reason and rejecting Scripture.
If these men were a help to Moses why then did Moses cry to God in Numbers 11:14 that the burden of the people was to much?
Jethro's great advice did not work!
God gave the Holy Spirit to 70 other men to ease Moses's burden.
Moreover, Jethro did not even stay with the Jewish people but left.
The critera for leadership in God's work is being filled with the Holy Spirit, not natural ability (as Jethro advocated).
