Skipping Sunday Mass? Is it Really a Mortal Sin to Skip Mass?
“But Father, I Only Skip a Sunday Mass Occasionally.”
By Fr. Ryan Erlenbush, The New Theological Movement:
Is it really a mortal sin to skip Sunday Mass?
Pope Innocent XI has condemned the following proposition: “The precept of keeping Holy Days is not obligatory under pain of mortal sin, aside from scandal, if contempt is absent.” (4 March 1679)
Thus, it is the teaching of the Catholic Church, that it is always a mortal sin intentionally to skip Mass on Sunday or on a Holy Day without a serious reason. Catholics are obligated to attend Mass either on Sunday itself, or on the Saturday evening
