It all deepens if u can tell which home is catholic house it a none catholic house but the one thing u don't do is just assume what they are and kindly ask and the home owners don't really have to be catholic or none catholic the home owners could be Puerto Rican or Jamaican or American or any other nationality the home owner is
though there isnt any bolded words in you question i assume you mean “mi amigo juan y yo” in english thats my friend juan and I, which could be replaced by we. We in spanish is nosotros.
