Intinction
Intinction is the Eucharistic practice of partly dipping the consecrated bread, or host, into the consecrated wine before consumption by the communicant.
Western Christianity
It is one of the four ways approved in the Latin Rite of the Roman Catholic Church for administering Holy Communion under the form of wine as well as of bread: "The norms of the Roman Missal admit the principle that in cases where Communion is administered under both kinds, 'the Blood of the Lord may be received either by drinking from the chalice directly, or by intinction, or by means of a tube or a spoon' (General Instruction of the Roman Missal, 245). As regards the administering of Communion to lay members of Christ's faithful, the Bishops may exclude Communion with the tube or the spoon where this is not the local custom, though the option of administering Communion by intinction always remains. If this modality is employed, however, hosts should be used which are neither too thin nor too small, and the communicant should receive the Sacrament from the Priest only on the tongue" (General Instruction of the Roman Missal, 285b and 287).
