What about the flag?

In many churches in the USA, the national flag adorns the worship space leading to numerous debates and divisions in church meetings.  If a congregation decides to keep the national flag in the worship space, these words might be posted nearby to facilitate the transcendence of the political statement and express a greater meaning:

This flag hangs in gratitude to
the United States of America
that grants us freedom of
religious practice and expression.

Also, this statement could potentially help a visitor from another country feel more welcome.
