St. John Chrysostom taught that the evil one tempts us when we are alone (as Jesus was alone in the wilderness). When we are surrounded by the community of the faithful, we are much less like to succumb. As he says, "flock together continually, that we may not be open to the devil’s attacks.” *
A great reason to flock to church on the first Sunday of Lent.
*St. John Chrysostom's Sermon 13, on Matthew 4:1.
