In this regard, I would like to call attention to a pastoral problem frequently encountered nowadays. I am referring to the fact that on certain occasions – for example, wedding Masses, funerals and the like -- in addition to practicing Catholics there may be others present who have long since ceased to attend Mass or are living in a situation which does not permit them to receive the sacraments. At other times members of other Christian confessions and even other religions may be present. Similar situations can occur in churches that are frequently visited, especially in tourist areas. In these cases, there is a need to find a brief and clear way to remind those present of the meaning of sacramental communion and the conditions required for its reception. Wherever circumstances make it impossible to ensure that the meaning of the Eucharist is duly appreciated, the appropriateness of replacing the celebration of the Mass with a celebration of the word of God should be considered.
