That is what we are asking their are many aspects to the Law, For instance keeping the Sabbath, well all of the Law regarding the sabbath or just the Sabbath day?
The Sabbath entailed not just keeping the 7th day, but also the 7th year and then on the 50th year the year of Jubillee, so all aspects or part or do you mean just the 10 commandments.
The taxation that the jews had was extreem, nearly 70% of their income was called for in some of their tithes scripturally required do mean all those aspects?
Since God has placed us under Grace and Grace giving then, 2 Corinthians 9: 6 But this I say, He which soweth sparingly shall reap also sparingly; and he which soweth bountifully shall reap also bountifully.
7 Every man according as he purposeth in his heart, so let him give; not grudgingly, or of necessity: for God loveth a cheerful giver.
8 And God is able to make all grace abound toward you; that ye, always having all sufficiency in all things, may abound to every good work:
This is how God expects the church to give now so would we then be violating scripture to go back under the tithe?
The OP is a bit vague on exactly what you mean at least to me and it seems to a few others.
