The Eucharist is the center of our Mass uniting us to Christ. It’s our desire that all Catholic’s of proper age, are able to receive Communion. Holy Communion may be received by “Catholics living in full ecclesial communion who are properly disposed, free from mortal sin, and have fasted for one hour from food and drink, except water, save for extraordinary situation”.
