That's horrible. If the mass is complete why have any other service? Or do the Catholics still do things like matins or vespers or compline? I'm sure they do in monasteries, right? But why if the mass is all-sufficient? Or why pray at home either by yourself or with your family? Does he prohibit Adoration of the Blessed Sacrament? Praying the Our Father or Hail Mary? Saying the rosary? Unbelievable.

(NOTE: I am not a Catholic.)
