The IRS made headlines this week with a quiet but significant policy shift: Churches can now formally endorse political candidates without risking their tax-exempt status. At first glance, this looks like a monumental change in the balance between religion and politics.

The Internal Revenue Service made a statement on Monday that would allow churches to support political candidates of their choice without losing their tax-exempt status, overturning decades of precedent in a recent court filing.

The rule was introduced by former President Lyndon B. Johnson in 1954 when he was serving as the U.S. Senate majority leader. It banned all tax-exempt organizations like churches and charities from “directly or indirectly” participating in politics, specifically in endorsement or opposition of candidates.
