My mother and I did not know you could report mis use of the tithe. However, my mother actually disagrees. She says they need as much money they can get to keep up the church, there are very few members and there are bills to pay.
We're supposed to pay tithe, scriptures in the Old Testament support. We give God 10% of our income.
*The church leaders are misusing the tithe, and if they are misusing
the money that's being given, then that's part of the reason the bills aren't
being paid and other folks aren't joining the church etc.
If financial misdeeds are known and not addressed or, even worse,
covered up, then that may require you to join with other believers
and request appropriate authorities to investigate the situation.
Your decision to leave could eventually hinge on the outcome of the investigation process and subsequent responses by fellow believers.
Your offerings/tithes etc...
You can set aside tithes until the investigation is completed or you
can give the money to a reputable Christian charity.
Tithing is an Old Testament concept.
The tithe was a requirement of the law in which all Israelites were to give 10 percent of everything they earned and grew to the Tabernacle/Temple (Leviticus 27:30; Numbers 18:26; Deuteronomy 14:24; 2 Chronicles 31:5).
In fact, the Old Testament Law required multiple tithes which would have pushed the total to around 23.3 percent, not the 10 percent which is generally considered the tithe amount today.
The principle in the New Testament is to give voluntarily to support the needs of others (Acts 2:45; Romans 15:25-27), support Christian workers (1 Corinthians 9:11-12; 1 Timothy 5:18), and expand Christian outreach (Philippians 4:15-16).
No specific amount is ever commanded, and no percentage is suggested.
While a tithe or tenth of ones finances may be a good standard to use for Christian giving, it is clear the early church did not focus on a specific amount but rather on meeting needs.
This sometimes included giving much more than a tenth, as some
believers sold homes or land to meet the needs that existed in the church
(Acts 4:34-37).
Supporting "the church"...
Each man should give what he has decided in his heart to give, not reluctantly or under compulsion, for God loves a cheerful giver (2 Corinthians 9:7).
