Novus Ordo people need to be treated like converts/protestants. They are no better than that. They have very little Catholicity, if at all, in their background. For sure they need a catechism course, along with checking their sacramental background (baptism). The True Faith and its beliefs and practices is way different than what the New Church offers. Such people need to catch up and adapt/convert before receiving Holy Communion. They must first be allowed to see what they are getting into and if they agree to truly be "True Catholic."
