I'm going to respond to your links in reverse order. From this one:
www.iiccworldview.org/individualism-and-...some-misconceptions/
- comes the money quote:
Convoluted financial arrangements are not uncommon in collective cultures where the group creates loyalty through the use of wealth. The seaming selflessness is, in fact, very destructive, causing tension between individuals, creating feelings of resentment and leading to extensive debt to outside organizations.
And from that statement you can see the basis in which rests the opposition to expanding the generous welfare state and the allegation that the party of Democrats is using the general treasury to purchase loyalty through the use of other people's wealth.
In scripture Christ confirms what Jefferson, Locke and others sought to express when they talked of natural law. Associations are voluntary in nature, even our association with our Creator is one that is voluntary. We are free to walk away from it, turn our back on Him who created us in His image and disavow any allegiance to Him or even acknowledge that He exists at all. The colloquial expression is "free will". Being a follower of Christ and His teachings means sacrificing yourself for the benefit of others. When our neighbor needs help, we show up, even if we want to sleep in that day. When one is ill we care for them, even if it means we get no sleep for our own body. When one is imprisoned we visit them so that they don't feel forgotten, or abandoned, or succumb to despair. When a cupboard is bare you share what you have, even if it means less for yourself.
But, and it is an important but, these decisions are ones you must make for yourself. Abandon your life so that it might be saved. Sell all you own, give it to the poor, and follow me. This is a recurring theme throughout the gospels.
Remember the story of the rich man that asked Jesus what he needed to do to inherit eternal life? I think it's in the Gospel of Mark, Chapter 10 IIRC if you want to look it up and refresh your memory. Anyway, Jesus said the man lacked one thing, that he needed to sell all he owned and give it to the poor, then he would have riches in heaven and to then come and follow Him. The question is why is that what the man needed to do? Is it because the rich have an obligation to the poor in a collective society, to provide for their welfare with the fruits of their efforts? Or was it because Jesus saw that even though the man had obeyed the law all his life, the one thing the man lacked was a love and devotion to God that superseded his love for his wealth; and that the only means of correcting that imbalance for that man was to get rid of everything he owned and learn what it meant to love God as opposed to simply obeying God?
Money isn't the problem, what one does with their money isn't the problem, it's what large amounts of wealth do to the spirit that separates God's children from their Creator. This is demonstrated in the teaching at the temple where the woman who put two small coins into the treasury while the rich put in large amounts. Mark again, Chapter 12 I believe. Jesus called his disciples to him and told them that the woman had given more than everything the rich had given because they gave of their surplus while she had given to others what she needed to live. She did that out of a love for others, a love for her God, that transcended even her love of her own life.
And I think both of these are examples of the iceberg analogy from your first link, where there is much more below the surface than one initially sees. Yes, when Paul was writing to those in Corinth, the you was plural and the temple singular. He wasn't writing to one Corinthian, he was writing to the Church in Corinth. However, salvation is an individual choice, it is one you must make for yourself. You must decide that your love for your Creator is greater than your love of your money, no one other than you can make that choice. Having your wealth taken from you by an outside force for the good of the collective doesn't accomplish the same goal as you giving of yourself for the benefit of others.
Salvation is never collective, it is always singular. Your salvation can't be accomplished by my actions, only by yours. You can lead a donkey to water, but you can't make it drink any, or something like that anyway. My deciding to sacrifice your wealth for the greater good doesn't bring you salvation because it accomplishes caring for the poor, the sick, the lonely, the imprisoned, the shoeless, the homeless, the hungry. Associations are, and must remain, voluntary for them to have any merit. What good is accomplished if I am forced to act in accordance with what society has deemed best? Does it soften my heart or harden it?
The answer, to bring this full circle, lies in the concept quoted at the beginning of my response. Charity, by its very definition, is a voluntary endeavor. Requiring your child to shovel the snow for the elderly neighbor might build character, but it is also just as likely to build resentment. Going out into the snow yourself and shoveling the snow for the elderly neighbor teaches your child that they have a societal obligation in the hopes that one day, when you grab your shovel, your child also grabs one and comes to help you help the elderly neighbor. When your child chooses to grab the shovel and help you help others they are being charitable. When you require your child to grab a shovel the end may be the same, but the way the end was achieved is wholly different and not nearly as beneficial to the child or to the community because once that child is no longer being required to help their elderly neighbor by you, they are not likely to continue to help.
Using the force of government to compel people to do something for the benefit of others at the expense of themselves is not a legitimate role of government. It takes from the person their ability to choose how they will act and destroys, not builds, a fond attachment to others in the society. There is a reason that charitable actions today are much rarer than charitable actions were prior to the rise of the welfare state. We don't give to charity, we don't participate in charity, we pay taxes so that others can address the problems and we don't have to worry about them. That doesn't build a community, that doesn't help unite us together into a single temple. What it does instead is allow us to be content with how much we tossed into the treasury.
