By Fr. Jerry Pokorsky, Catholic Culture - Jesus sends out His 72 advance men to prepare the way for His coming. It’s a good guess that the disciples are in training for the priesthood. They travel light, eat the food placed before them, proclaim the Kingdom, and if the people do not receive them with respect, they knock the dust off their feet in testimony against them and move on to the next city. Their work prefigures the Liturgy of the Word and anticipates the Liturgy of the Eucharist... The Mass has two main components: the Liturgy of the Word and the Liturgy of the Eucharist.
