There is a longstanding tradition in the Church of having the faithful fold or “cross” their arms over the chest as they approach the chalice to receive Holy Communion. This was originally instituted to prevent anyone from doing anything with their arms which, might bump or disturb the chalice and spoon as the priest is distributing the Eucharist.
Folding one’s arms right over left on the chest helps prevent the chance of any accident or mishap, and is also a gesture of humility and reverence before God; much like the sinful Publican in the parable who beat his breast and asked for God’s mercy or the angels who fold their “wings” as they bow in prayer.
Those approaching the chalice should practice caution by not attempting to bless themselves either before or after receiving Holy Communion, as this might also upset the chalice. If you are holding a small child or lifting a toddler up, be careful to hold their arms and legs tightly so they do not flail them and present a hazard.
The motto regarding the chalice and the precious Sacrament contained therein should always be: “To Protect and Preserve!”
