“We are not peddlers of the word of God as many men are, but we speak in all sincerity as sent from God.”
~2 Corinthians 2:17

Jesus said, “You received free, give free.” (Matt. 10:8)
He made it clear that the congregation was not for commercial purposes. (Matt. 21:12,13)
While the congregation did accept and redistribute monetary aid, no one should feel obligated to donate or be put on the spot for it. (2 Cor. 9:7)
It is inevitable to notice that some religious pastors who charge tithes have luxurious homes/lifestyles while members of their flock have to take in boarders to pay the rent and cannot afford to finish school.
The Christian congregation can be identified by love of neighbor, so true Christian ministers sacrifice their own assets for the spiritual wellbeing of others, instead of expecting the community to provide for them. (2 Thess. 3:8-10)
