I'm still trying to grasp what a Church needs a Mac (let alone a PC) in order to spread and preach the word of god? Haven't the last few centuries produced enough bibles in physical print to go around about 5x per person in any major city? And FileShare, VPN, what on earth does a Priest or the clergy need these things for??
In case this is not facetious (and for the benefit of those who have not stepped into a church recently), many churches rival small (or even large) companies in terms of their IT requirements. Churches have staff, whether paid or not -- pastors, secretaries, musicians, children's workers -- and they typically have computers and printers, and file shares. Many churches run their own websites ranging from as simple as a digital brochure to a site that can live-stream their services or stream recorded sermons from cameras in the sanctuary.
The sanctuary itself will require computers to run the lights (DMX controllers usually), the projected slides, LCD monitors mounted in the hallways outside, nursery rooms, etc. Larger churches may have even more LCD monitors driving stage or even back-stage displays.
Typical church networking use cases:
- pastor prepares sermon slides on his computer, sends them to sanctuary computer for display
- pastor wants to show the latest viral YouTube video during service
- worship leader prepares slide sets, calls up recorded audio, lyrics, etc. for rehearsals, sends final slide set to sanctuary computer for display
- AV tech records audio or video of service and posts it on website
- website frequently updated with blog, photos, announcements, etc.
- looping "announcements" slide show is prepared and shown on multiple displays around the building
- internal VOIP based PBX system for inter-office communication
- storage of private records -- counselling data, financials
- wifi access for staff (and sometimes congregation)
All of this can be done with PCs of course, it is just personal preference.
My church bought an iMac in order to run a software package called ProPresenter which allows real-time random-access playback of slides, video, photos, etc. Although there is now a Windows version so there would be less of a push today to go Mac.
