Altar Servers will extend the sign of peace to each other, the Priest, and Deacon. Return to the credence table and bring the two small chalices with Purificator and bring them to the Altar. The Priest will fill the chalices. When he is finished, return the flagon to the credence table.
Once those tasks are completed, move to the right side of the sanctuary facing the congregation. Once the Eucharistic Ministers are on the Altar, extend the sign of peace with them.
Note: the Eucharistic Ministers may be moving around the sanctuary to bring out additional ciboriums, etc. Be prepared to assist them if needed.
