How did the Walk to Emmaus movement begin 

The walk to Emmaus is an adaptation of the Roman Catholic Cursillo (pronounced cur-SEE-o) Movement, which originated in Spain in 1949.  Cursillo de Cristianidad means "little course in Christianity."  The original Cursillo leaders designed the program to empower persons to transform their living and working environments into Christian environments.  During the 1960's and 1970's, the Episcopalians and Lutherans, along with several non-denomination groups, such as Tres Dias, began to offer Cursillo.  In 1978, The Upper Room of the General Board of Discipleship adapted the program for a primarily Protestant audience and began to offer it under the name The Upper Room Cursillo.  In 1981, The Upper Room made further adaptations and changed the name of the program to The Upper Room Walk to Emmaus.  In 1984, The Upper Room developed a youth expression of Emmaus called Chrysalis.

The above story provides the image for Emmaus, an Upper Room program that calls forth and renews Christian Discipleship.  Like its predecessor, Cursillo de Christiandad (Spanish for "short course in Christianity"), the Walk to Emmaus is a three-day experience which takes a New Testament look at Christianity as a lifestyle.  It is a highly structured weekend designed to strengthen and renew the faith of Christian people, and through them, their families, congregations and the world in which they live.  Emmaus is a combined effort of laity and clergy toward the renewal of the church.
