The Eucharist is the source and summit of the Christian life.(LG no 11)
1. Our dignity as baptized children of God.
“For all of you who were baptized into Christ have clothed yourselves with Christ.”
2. The sacredness of the Church as the House of God and the Eucharistic celebration urge all participants to dress and manifest the importance of what they are doing.
“The mystery of the Eucharist has found historical expression not only in the demand for an interior disposition of devotion, but also in outward forms meant to evoke and emphasize the grandeur of the event being celebrated.”
[Ecclesia de Eucharistia, no. 49]
