 ::::Hi User:Ign Christian, I appreciate your reply. I understand that you're not here to violate rules and I hope this discussion has been helpful to you. I wanted to address both of the issues that you speak of. The source you preferred, Unitatis Redintegratio, from the Vatican's website specifically states ""Though the ecclesial Communities which are separated from us lack the fullness of unity with us flowing from Baptism, and though we believe they have not retained the proper reality of the eucharistic mystery in its fullness, especially because of the absence of the sacrament of Orders, nevertheless when they commemorate His death and resurrection in the Lord's Supper, they profess that it signifies life in communion with Christ and look forward to His coming in glory"" (italics added). That being said, the issue of valid Holy Orders is inextricably linked to the issue of apostolic succession. Going into this discussion in the Mass (liturgy) article, however, is not necessary since that is not the primary topic of the article. Furthermore, we do use the word ordinarily. The Guidelines For The Reception Of Communion Guidelines For The Reception Of Communion published by the USCCB state ""Because Catholics believe that the celebration of the Eucharist is a sign of the reality of the oneness of faith, life, and worship, members of those churches with whom we are not yet fully united are ordinarily not admitted to Holy Communion. Eucharistic sharing in exceptional circumstances by other Christians requires permission according to the directives of the diocesan bishop and the provisions of canon law (canon 844 §4)."" The usage of the word in English simply means that it is not the norm for Christians of other denominations to receive the Holy Eucharist in the Catholic Church, except in certain circumstances detailed by canon 844. As such, the current wording of the article seems quite appropriate. I hope this helps and look forward to hearing your thoughts. Thanks,  "
