For God has promised that none of his faithful ministers would ever be guilty of adultery! But Garner Ted was not the only “minister” or hireling to fall from grace. He was one of the most high profile to fall into the depths of depravity. However, many were guilty of drunkenness, asbuse of power and, of course, greed.
Anyway, God's faithful ministers are integrated into the head of the body, that is why they are commanded to feed the flock with sermons inspired by Christ(2 Cor.3:5). Just as Christ fed his disciples with messages inspired by his father(John 14:10).
Also, the ministers of the NT church are chosen by Christ in accordance with will of God thus: "Who," that is, Christ, "also has made us able ministers of the New Testament, not of the letter, but of the spirit...(2 Cor.3:6). An able minister is a person who has the character and ability to educate and care for God's people. That is why the Apostle Paul saw it as his job, "to make all men see what is fellowship of mystery, which is Christ in you, the hope of glory"(Eph.3:9 and Col.1:25-27).
Can any sensible person really believe that the hirelings operating in cog-land, burdened by duplicity, coventousness, greed and insatiable desire for power, understand the fellowship of the mystery? Not in a million years!
