I've spoken with individuals who consider themselves estranged from the Church. Sometimes their situation has come about as the result of hurt suffered at a sensitive time in their lives, or a brush with someone seen as representative of the Church, or more often than not a case of disillusionment or a sense of not fitting in.
It's hard to convince such a person that it is infinitely better to be part of the Church, with all its imperfections, than to cut oneself off from it. How can we expect to get somrthing out if we put nothing in; what good are our talents if we keep them to ourselves, hoarded away like money in a cash tin? A Church community thrives when those within it pool together for the greater good.
Everyone has something to offer God, and something to share for God's sake. By coming together to worship Him, we can stumble upon hidden gifts and at the same time become healed of the hurt and division which otherwise would keep us apart.
There will be no fanfare for an estranged soul coming back into the fold (at least none we can hear) nor will it be roses all the way, but there is for them what there is for us, namely, real communion and confirming of our identity as children of God.
