You were invited if you lived in the house. Not everyone can join. People got to know you first (and then how could they resist? : )
The door should be open if it is a Christian thing. No tickets to Saint Patrick’s (well, except for special events).
What I meant to say is that I went to daily prayers after contacting the Midtown Center in Chicago, volunteered for activities, and then went to live in the house. I got along wonderfully with the priests, less so with the lay members (aside from a very good friend).
