I'm not very much in the same situation as you I'm not a very religious person ...
(but still have great interest in legends, mythologies , spirituality and such)
I believe there is no problem at all to but your therianthropy in prayers , I believe God is a spiritual being (not the one in shamanism I'm talking about church)
Who is above all pure=good spirit , and we were-cats (or any therian what so ever )
Are not evil creatures .
But i believe maybe you shouldn't mention this is church to someone at random ,
Ive notice allot (ever since i was a child) that humans :
(i mean ''Pure''-Humans...non-therian)
Have the destructive nature to feel Superior and stick to tear beliefs ,
and basically they are scared of what we are and everything that is unknown ,
and Ive heard that they would consider a ''werewolf'' as a beast , a demon and so on...
(we are beast ...but i mean animal nature ,not demons)
Besides my mother (who I'm pretty sure she doesn't believe/understand me )
and my best friend ,
(who i trust very much , and try to trust her with my reveilance of my therianthropy )
Ive only told an other therian (a friend of mine) who is a wolf therian .
...
Usually pure-humans have a jugging nature and everything that is different is just plains blizzard
And they cant accept it ...unless they are .
So I'm not saying you really shouldn't ...but think about it ...please I'm just telling you this to try to avoid being called ...crazy ...
(i believe thats one of my old friend almost said to me as a young child wen i told him i had this weird type of connection with animals wen others did not ...)
Maybe this is just me ...i don't feel very comfortable at church ,
( maybe i felt to forced into it as a young child . not sure
)
But make a wise choice , to whom you will tell it too ...
someone very opened minded perhaps...
anyway , best of luck
