I spent my formative years attending the Amherst Foursquare Church. It pains me to type the word, “Amherst” because they were the arch-rivals of my hometown, Vermilion, idyllically situated on the shores of Lake Erie.
Anyway, the Foursquare Church is a Pentecostal denomination of a few million started by the early-century revivalist Aimee Semple-McPherson (who was a fascinating individual and figure). I never knew what all the fuss was over women’s ordination! My experience in the church was good and bad and I’m glad I grew up there.
So, one of the tenants of belief held by the Foursquare Church that I have come to appreciate is this:

Moderation
We believe a Christians’ moderation should be obvious to others and that relationship with Jesus should never lead people into extremes of fanaticism; their lives should model that of Christ in uprightness, balance, humility, and self-sacrifice (Colossians 3:12, 13; Philippians 4:5).

It seems a bit ironic that Aimee penned this tenant, because, well, I suppose it was a tenant she hoped to live into because her life seemed not quite moderate. Moderation in all things – lives model after that of Christ consisting of balance, humility, and self-sacrifice. This is a good word.
