I actually believe that tithing involves much more than 10% [First fruits, sabbatical and jubilee years, freeing slaves and foregiving debts - are all associated with giving to God] but Sepharad could speak to that in greater detail I think …
The funny thing I think of when christians discuss tithing … that’s OT, etc ----- NT says … we are to give from our hearts - joyful giving, etc … ] is that we believe that we should [can?] start at zero …
For the gift of God to man which was - Moses, the Law and the Prophets … a proscribed tithe [of 10%] was given … I am sure that God desired the Hebrew people to give joyfully and from their hearts …
As Christians we have Moses, the Law and the Prophets PLUS the Messiah, Salvation, the forgiveness of sins, the Church, the Sacraments [epsecially Baptism, Reconcilliation and EUCHAIRST - the very Body and Blood of Christ!], the New Testament … and we give ?? … ?? … 0% … uh whatever feels good to me today …
Jesus tell of the widow who gave 2 mites from her need. That small gift was far more than the 10% given by the Rich Man from his abundnce …
We are to give from our need … a gift from our abundance is not truly a gift … it is just left overs … All of our wealth [health, happiness, talent and intelligence] all come from God …
It is not hard to get to 10% plus of gross when you make thanking God for your gifts a priority …
No the church does not demand it … the gift should come from your heart …
We target 5-6% for our parish [some of which goes to Social justice out reach] and 4-5% other charitable causes … at the end of the year we usually hit about 12-17% and we cannot capture all charitable donations… and of course this does not take into account other parish support via fund raisers like spaghetti and other dinners, script sales, book fares, car washes, food items …
