The prevailing view among Protestants and/or other Christian denominations is that they don’t want their church to be either poor or wealthy.
The foundation of this idea is easily explained. A careful understanding of the New Testament proves that ambitions built on money are not only frowned upon, but viewed as a weakness of character. Additionally, most congregations view the lack of adequate funds as a sign of humility.
The Mormon Church requires a 10% tax upon their members. They call this tithing, but it is a payment to remain a member in good standing and worthy in the Church; it is also lauded as a commandment. Members are asked to have a yearly review of their contributions in a private meeting with their bishop. Latter-day Saints might argue that it is not ‘required,’ but there is little doubt that members who will not pay tithing do not progress in the LDS faith.
The irony of this circumstance is that the Mormon Church unashamedly utilizes the contributions of members in many ways, and they don’t disclose specifics about their financial dealings. Though they don’t voluntarily offer their financial statements to be reviewed by anyone, the members don’t seem to demand it of them either. The average Mormon is happy to know that the Church is heavily invested in real estate, and that there is a new chapel or temple showing up soon.
