My nephew just move across the street from a church doing a similar thing (but not the microchip). You must bring in your income tax statement to verify that you are truly giving 10%. While I abhorred such tactics the church is growing.
And how does your income tax statement provide verification? Perhaps they think a Christian is less likely to lie to Uncle Sam than to God.
Those who require this will burn in Hell.
I had a 'church leader' call my boss once to find out exactly how much I was making to make sure I was paying the full 10% as they required.
He also wanted me to bring in my tax returns and when I said no, he tried to get them from my accountant, who promptly laughed in his face.
Interesting, since no where in the New Testament is a believer commanded to give 10% of anything.
The tithe in the Old Testament was actually three “tithes”, and amounted to 23% of your annual income.
I would never do that. Some people feel the need to be watched, taken care of, etc. and that’s makes them feel they are on the right path. Deception comes in many forms.
