So much I could say. Ministry is a calling. one of the requirements Jesus once told the disciples to go out without script or bread. I think from this we hear him saying, "I want you to rely on me". In another place when we read, " muzzle not the Ox that treadeth out the corn". however certain ministries today barely even subtly teach your answer is waiting in the size of the ($) "seed" that you plant!. One thing that I'm sure of is that in the early church, the ministry shared the offering, and tithes. no one lacked. What came in to the church was shared by all. In some scriptures it suggests they had all things common. I'm sure the elders watched over the proceedings, and yes slowly it became clear that some were greedy. some were seeking to benefit. There has been a great turnaround to the bad I believe in our modern licensed churches. They present the idea that there is a class separation in the church. It is very obvious in many churches that someone "rules" and all else are to follow, or be ostracized. through my life I have witnessed so much greed through religion that its appalling. I've seen individuals declare, "that money is all mine because I am the pastor". I've seen the group worship the leader like he was God or close to it. Respect and Reverance can get out of control. When the one who is biblically the "Shepherd" he is to use all of his resources and energy to lead and help the "sheep". Jesus is actually the True Shepherd. Just because you are a pastor or a leader in the church doesn't give you special "class" rights of society. As your reference Scripture, Paul states "we don't preach about ourselves, We preach Jesus, and Him crucified!". Other scriptures show that these Gospel Apostles, and disciples took their calling seriously. They left all to Follow Christ. Some today rather follow for what they can get. No, its not necessary if you are a minister to take an oath of poverty. But you better well be Serving others and have a heart of giving. For that is what the Gospel is all about. Peter at the Gate beautiful to a man who was lame. reaching out to take his hand, spoke his conviction "silver and gold have I none, but such as I have give I unto thee. In the Name of Jesus Christ, ( the Son of God), Rise up and Walk!)" I admit, its very hard sometimes to walk in a manner worthy that God will honor your works and your words, but Peter apparently had that kind of relationship, to see those miracles happen.
