Should you find yourself on another planet, and should you meet an intelligent being there, with whom (mirabile dictu) you find you can communicate, what do you do next?
You have no doubt often wondered about this. Here is the answer.
First you ask, "Has there been a Fall here?" If you receive the answer, "No," leave straight away before you mess things up.
But, if you receive the answer, "Yes," you go on to ask, "Has there been an Incarnation?"
If the answer to this is, "Yes," you make this request:
"Please direct me to the nearest Catholic Church."
