This isn't Christianity, it's just Catholicism. Why would someone who has castrated themselves be barred from ministry? What promotion are they even talking about? There is no Biblical basis for "promotion" in ministry... It's just mind-boggling how they just pull nonsense out of their rears. If someone castrated themselves, they can still be used by God to further His kingdom. They can still serve people, feed the hungry, clothe the cold, and encourage the downtrodden. It's just nonsense...
