The spirit of the Chapel is well expressed in the mottoes inscribed on its walls and shown below.

"The Church is Many as the Waves, but One, as the Sea."

Suggested by the Honorable James Leland Howard, a founder and early President of the Chapel.

"In Essentials, Unity: In Non-Essentials, Liberty: In All Things, Charity."

Attributed to Petrus Meiderlinus (1592-1651), a Lutheran priest. It reads: In necessariis unitas, in non-necessariis lebertas, in utrisque caritas.
