Not sure where we see capitalism in scripture ...
To say God supports capitalism...(not taking about property rights, market economy etc. , ) would mean to me that it occurred in scripture, however I have not read any situation where there is an example of capitalism?
You will not find the word trinity or Jesus literally say I am God. As also you will not find the exact word capitalism. But in context and scriptural support we can come to such conclusions.
Capitalism is an economic system based on the private ownership of the means of production and their operation for profit.
I believe private ownership, using this as means to sustain ourselves, to help poverty one must have excess to give. Scripture talks about a farmer should leave the corners of their fields for the hungry. Also 10% to the church which is best fit to help the poor, the sick, or the lost. Then everything else went to profit.
There are many examples of God's blessings within private property and how the people of God often became quite wealthy in doing so. Job being one example. God even promising if His people would follow him they would be blessed in the field. Also that people must provide for family. That if able bodied person doesn't work they shouldn't eat. Scriptures on obeying neighbors land markers. Scriptures on protecting and judging the act of burglary.
Profit isnt bad. It was the love of money that was bad.
The Bible gives us insight on every concept in life.
A free market involves liberty. Liberty is defended in scripture and mentions one should secure their freedom if possible.
There is better incentive to work if one has liberty but also has the ability to sustain and support their families.
Scripture talks about taxes too. We should give to Caesar what is Caesars and give to God what is required. Scripture also shines light on those who abuse tax rates and how the people hated them.
