congregation. Traditionally only those within the Office of the Holy Ministry distributed the Sacrament, but it has become common for lay people to assist in the distribution. The host is commonly a thin unleavened wafer, but leavened wafers or bread may also be used. Traditionally, the minister placed the host on the tongue of the communicant, with the communicants not even touching the base of the chalice as they received the Blood of Christ. More recently, it has become common for the laity to receive the host in the hand. Some parishes use intinction, the dipping of the host into the chalice. The wine is commonly administered in a chalice, but many congregations offer individual cups as well. These may be either prefilled or filled from a pouring chalice during the distribution of the Eucharist. Some ELCA congregations make grape juice available for children and those who are abstaining from alcohol and some will accommodate those with an allergy to wheat, gluten, or grapes. Upon receiving the Body and Blood, it is common for communicants to make the sign of the cross.

Many people kneel when they practice this adoration. The consecrated elements are treated with much respect and in many areas are reserved as in Eastern Orthodox, Roman Catholic, and Anglican practice. The Feast of the Corpus Christi was retained in the main calendar of the Lutheran Church up until about 1600, but continues to be celebrated by some Lutheran congregations. On this feast day the consecrated host is displayed on an altar in a monstrance and, in some churches, the rites of the Benediction of the Blessed Sacrament and other forms of adoration are celebrated. Liturgy The Lutheran worship liturgy is called the "Mass", "Divine Service", "Holy Communion", or "the Eucharist." An example formula for the Lutheran liturgy as found in the Lutheran Service Book of the LCMS is as follows: The "Great Thanksgiving" or Sursum corda is chanted or spoken. Next, the proper preface is chanted or spoken by the pastor. Below is an example: This is followed by the Sanctus, which is sung by the congregation. Next, the first part of the Eucharistic Prayer is spoken by the pastor. The pastor then says the Words of Institution. The pastor
