Dear Father Rutler,

Twice a month I attend a meeting of fellow knitters and needle-pointers. Usually the conversations are focused on family news, health matters, etc. More recently, however, the subject has turned to weightier issues like same-sex marriage and abortion. I haven’t yet involved myself in these discussions, as it’s increasingly clear to me that I’m the only practising Catholic in the room. Have I committed a sin of omission? What should the Catholic response be in such cases?
