According to a 2015 Pew Research study , about half of American adults who grew up in Catholic households have left the Church at some point (with very few ever returning). Sister Karen is quick to tell us that she understands why young people would rather identify as spiritual but not religious , but they may have more God in them than they realise."They don’t see their voices being heard and they don’t think that their voice can have an impact in the Church today," she says. But, millennials who volunteer within their communities, rally against oppressive laws, or simply support others are living a spiritual life: "They are doing the work of the gospel," Sister Karen says. "They just don’t always recognise that, because their early faith teachings probably didn’t provide them with an open interpretation of the gospel."If you're among those who left the Church at some point but wish to reconnect with your faith, it's easier than you think. For one thing, don't force yourself to go to Mass if you don't want to, Sister Karen says. "Give yourself time to find a relationship with God. Give yourself time to be receptive, and give yourself prayer time. It’s only through that quiet time that you can really see God in your life and your work."After that, it's up to you to swing by church or not.
