We're Catholic. We go to confession. We kneel before a priest in the darkness of the confessional, whisper our sins by number and kind, and hear anew those precious words of absolution.
We must go AT LEAST once per year (Can. 989). Mother Teresa and John Paul II went to confession once a week. So does yours truly.
Maybe it's been a while for you. Maybe you even forget how to do it. Make an examination of conscience, remind yourself what to say, and then go. Just go. Go today as if your soul depended on it because, dear catholic, it very well might.
