There are a number of people here (including myself) who have experience using whistles in Church music.
The main difference (it seems to me) between being an Irish traditional session player and a Church musician is the number of different keys you may need to cover.
Many whistle players who regularly play at Irish sessions show up only with a D whistle.
In traditional hymnody, that is, choir and organ (which is the Church music I'm most familiar with) keys from three flats to three sharps are common (Eb, Bb, F, C, G, D, and A) and you might see four flats and/or four sharps (Ab and E).
Yes each whistle can cover two Major keys (one based on the whistle's tonic, the other based on the whistle's fourth) yet oftentimes I prefer to use a whistle due to its range as much as its key. So D Major can be played on a D whistle and on an A whistle, and which I use to play a D Major hymn depends on the range of the tune.
I find, for traditional hymnal-based music, that at minimum I need whistles in Eb, Bb, C, D, and E.
As far as guitar-based Praise music goes, on the one hand many guitarists stick to basic guitar keys like G, C, D, E etc but on the other hand all bets are off if the guitarist uses a capo. You might play a song in D one day and in D# the next, another song in C one day and in C# the next.
Due to such things I ended up with whistles in every key, chromatic.
Modulating up one or more keys is common in Praise music. It's simple on whistle: when they modulate you just grab another whistle, and play the tune just as you did before.
