We have a number of protestant Christians who attend Holy Mass. We do not intercommunicate. In some cases they become regular members of our parish community often with Catholic spouses or friends. On a number of occasions these members decide to assent to the Catholic Faith.
At communion time we welcome all who are either not of our Faith or who are not properly disposed to receive spiritual communion remaining in their pew.
They are also welcome to kneel at the communion rail and cross their arms to indicate they request a blessing.
