 Christianity has the doctrine of the Trinity in which God is said to manifest as three persons the father son and holy spirit No, so it's not quite correct. It's not that God manifests himself, but rather that God has three persons This is the description of the Trinity within the creeds of orthodox and Catholic Christianity It's not so much a manifestation But rather an intrinsic part of God in every changing part of God so to speak three personas in One no disrespect here, but yes, we're speaking about a split personality If you will we're not talking about different manifestation or modes of existence But rather off a God that has always three different persons So it really is a split personality disorder if you will
