There are many firms operating in the United States that engage in practices that many Christians find unethical. Depending on your faith tradition and biblical interpretation tobacco, alcohol, and casino firms may fall into this category. Beyond the actual business that firms are engaged in, there are also firms that support in some way drug legalization, and many other policies and practices.

What is a Christian's obligation with the use of money?

• Should they only invest in firms that are supportive of their moral and ethical code?
• Should Christians work for companies that sell products that do not align with their faith?
• Consider the fact that tax money is used to support practices such as subsidizing tobacco farmers, casino operators, and so forth. Should Christians have a say in how their tax money is spent?
