Hearty and Honest Consent

Quoting Lutheran theologian Charles Porterfield Krauth:

To true unity of the Church, is required hearty and honest consent in the fundamental doctrine of the gospel, or, in other words, in the Articles of Faith.

...It is utterly false that Evangelical Lutherans are sticklers for non-fundamentals, that they are intolerant toward those who err in regard to non-fundamentals; on the contrary, no Church, apart from the fundamentals of the gospel in which her unity and very life are involved, is so mild, so mediating so thoroughly tolerant as our own.
