Let me point you away from the doctrines of men and let's see what is said about this subject in scripture:What percentage goes into paying the wages of your Pastor/other church staff?
Jehovah's Witnesses: NOTHING - they all work completely for free.
1 Timothy 5:
17 The elders who direct the affairs of the church well are worthy of double honor, especially those whose work is preaching and teaching.
18 For Scripture says,Do not muzzle an ox while it is treading out the grain, and The worker deserves his wages.
1 Corinthians 9:
14 In the same way, the Lord has commanded that those who preach the gospel should receive their living from the gospel.
