Today is the Memorial of St. Ignatius of Loyola. Gospel reading during Mass came from Matthew 13. Jesus in explaining the parable of the weeds of the field to his disciples mentioned himself (the Son of Man), the Evil One (the Devil), the angles, and the Father. At harvest time (the end of the age), Jesus will send his angels to collect all who cause others to sin and all evildoers to be punished.
I am struck by the separate category in which those who cause others to sin are placed. Normally, we are aware of our own sins, but we don't often think about whether they might cause others to sin. For example, if a father uses bad language, he doesn't think about how his son might pick it up from him. Obviously, the more people we cause to sin, the more severe our punishment will be. The best policy, of course, is to be aware that any sin displeases God and to stop sinning.
