Ok. I'll handle this.
The trinity is like three borgs ( who have a hive mind). One Borg left the cube ship and came to earth to be sacrificed. He died, but the other two resurrected his body and beamed him back up to the mother cube ship. He was still in the others when his body was killed, so technically he resurrected himself.
They can exist separately, but their minds are one. Boom! everyone leaves this thread happy. Now, back to Star Trek, which like the Trinity, belongs safely in the land of fiction.
