Caring for those of your own household and church is exactly what the Bible demands. Being forced to support the public at large is not.
Uh? What Bible says that? I don't see where God speaks of only caring for our own and those of just our church...in fact just the opposite...as follows:
Luke 6:33...... "And if you do good to those who do good to you, what credit is that to you?..... For even sinners love those who love them...... And if you lend to those from whom you expect to receive, what credit is that to you?....... Even sinners lend to sinners, in order to receive back the same."
So I don't know what Bible your using because the Bible contains more than 300 verses on the poor, social justice, and God's deep concern for both.
Deut. 26:12...... When you have finished paying the complete tithe of your increase in the third year, the year of tithing, then you shall give it to the Levite, ...To The STRANGER, to the orphan and the widow, that they may eat in your towns, and be satisfied.
Is. 58:66..... Is this not the fast which I choose, ....Is it not to divide your bread with the hungry, and bring the homeless poor into the house; when you see the naked, to cover him?
And let's not forget Paul saying....Gal. 2:9..." Recognizing the grace that had been given to me, James and Cephas and John... gave to me and Barnabas the right hand of fellowship, that we might go to THE Gentiles, and they to the circumcised. They only asked us to remember the poor-- the very thing I also was eager to do....(which were outside their faith)
And further socially....Luke 14:12-14...... "When you give a luncheon or a dinner, do not invite your friends or your brothers or your relatives or rich neighbors, lest they also invite you in return, and repayment come to you...... But when you give a reception,.. invite the poor,... the crippled,.. the lame,... the blind,... and you will be blessed, since they do not have the means to repay you; for you will be repaid at the resurrection of the righteous."
Furthermore my understanding of the Mormon church is many are "demanded" to give a tithe, and if they dont' there are repercussions for not keeping current.....that is not a church I would belong to for it flies in the face of what God says....2 Corinthians 9:6-9 “Remember this:... Each man should give what 'he has decided in his heart' to give, not reluctantly or under compulsion, for God loves a cheerful giver.
