It would be far better NOT to apply to the government (IRS) for their permission to be a non-profit that happens to be a church. Just be a Constitutionally-protected church.
Tax exempt status is not granted by 501c3 status; limited liability is. Churches are automatically tax exempt, but church leaders are personally liable for church activities (including tax liabilities). There are no restrictions on church speech unless the church puts themselves under the statutory obligations of incorporating.
This decision is much more onerous than most people understand and it should not be undertaken lightly. Why do churches accept the devil’s yoke? The leadership trades the protection of God for the protection of man—sons of their father Jacob.
