Book excerpt: Echoing the Mystery is a catechetical resource specializing in sharing the doctrines of the Faith. After the culmination of many years of catechetical teaching and engaging all ages to share these truths, the Dominican Sisters of Mary, Mother of the Eucharist joyfully present this beautiful master resource Echoing the Mystery. In a shared desire to compile and supply an all-encompassing source for ‘echoing’ the doctrines of the Faith, the Sisters have accomplished their long-held desire to transmit the catechetical teaching approach from reputable catechist, Barbara Morgan, finally presenting in one place, her decades-long teaching method of the keys to the doctrines. “Were not our hearts burning [within us] while he spoke to us on the way and opened the scriptures to us?” Luke 24:32 Echoing the Mystery, Unlocking the Deposit of Faith in Catechesis, aims to open the mysteries God has revealed to us. Through His Son, Jesus Christ, He has communicated to us His loving plan of salvation. In order for these Truths to be echoed down, they must first be studied and contemplated. This publication makes them accessible to anyone desiring to evangelize and catechize.
