Some people get very fussed over people who don't go to church often.
I've always thought that it's better to just welcome them when they do come, and trust that God will lead them to be there when they need to be and lead the rest of us to evangelise via our regular relationships.
This article takes it a bit further, and asks what the regular attending holy-joes can learn from the special-event-sallies about what really matters.
Work with what you have, not what you'd like to have.
Food for thought.
