Yes, an LPFM/NCE station can typically broadcast an underwriting message that encourages people to "attend church." However, it's important to ensure that the message remains within the guidelines of underwriting announcements and doesn't cross the line into a direct call to action. Underwriting messages should focus on acknowledging the support of the underwriter without urging immediate action from the audience. While promoting attendance at a church event may be acceptable, the message should avoid using language that creates a sense of urgency or insistence on immediate participation. It's always a good practice to review the specific wording with legal experts familiar with FCC regulations to ensure compliance.
While this approach could be suitable for churches, it may not be applicable to other religious enterprises like Christian bookstores or for-profit Christian schools. Businesses operating for profit, regardless of their religious affiliation, are bound by FCC policies, which include restrictions on making calls to action in their broadcasts.
