While I'm not a religious person, and you won't be seeing me give money to any church, it's not that simple. Firstly, the idea that you can calculate the loss in taxes by just applying the tax on paper is fundamentally incorrect, since the tax itself creates an incentive not to spend money that way.

Secondly, churches spend part of the money on social assistance, and so a reduction in their income may increase the funding needs for governmental assistance programs.

I'm not fundamentally opposed to cutting tax breaks for churches, but living in a country where recent tax increases have lead to a massive tax revenue reduction, I felt the need to point out that you probably couldn't fund 28 rovers with it.
