Does Platonism have a denomination/group/following within Christianity?

I wish to follow Plato's belief of the forms and find other's who do so. Erm, question is, in Christianity is that actually a 'thing'? CS Lewis followed Plato. Peter Kreeft does...so Christians CAN but, well, how to know if you're among those who support it and can talk freely? To clarify, the Platonist belief I am mostly interested in is the idea that everything has a heavenly archaetype that is more perfect than it, and that a bad thing made bad by being (to whatever degree) far away from its perfect, ideal form.
