Your comments about tithing are seriously flawed for many reasons.
First, the consistent biblical definition of a true HOLY tithe as used by Moses, Malachi and Jesus is only food from inside God’s holy land of Israel which He had miraculously increased. Although money was very common even in Genesis, HOLY tithes could not come from Gentiles, from outside Israel, or from non-food products.
Second, Acts 20:29-35 very clearly say that Paul worked to supply his needs and the needs of those with him. Paul even boasted of being self-supported and received absolutely nothing from Ephesus in 3 years. How could he at the same time teach tithing?
Third, the phrase “it is better to give than to receive” from Acts 20:35 is directed to elders, church leaders, from Asia Minor and not to the church members. In context, Paul was telling church leaders to work and give to their congregations –not the other way around.
Fourth, 2 Cor 9:7 and 1 Cor 16:2 are about freewill sacrificial offerings to help in famine relief. They are not about church support or church finance.
Gentiles and the church never were under the Old Covenant law. Let us not add the law back into grace giving.
