Megan Hill defends praying for big toes, and then goes a step too far:
When we pray together as the church, we should regularly and deliberately pray for the God-directed mission of the church: the advance of the kingdom, the strengthening of the body, and the exaltation of Christ.
But it is no mark of holiness to disparage the small and sometimes immature requests of those who are also in the body. As people who are being built up together into Christ who is the head, we have good reasons–kingdom reasons!–to sometimes pray together for dead birds and ill aunts and next-door neighbors who have had bad news.
It may not be a mark of holiness, but to reform a church you have to break some eggs (and wound some egos). Imagine if Luther and Calvin had thought criticizing the veneration of saints were marks of unholiness.
So why not make an argument based on Scripture or wisdom, rather than questioning the holiness of those who question the oddities of small group prayer?
