The preparation for the sacrament of First Eucharist involves the pastor, parents and/or sponsors, and catechists of children, supported by prayer and ritual with the parish community. During their preparation, candidates not only learn the truths of faith regarding the Eucharist, but also how to participate actively. Thus, "children should be taught the Holy Eucharist is the real body and blood of Christ, and what appear to be bread and wine is actually His living body" (NCD #122).
Religious formation programs provides immediate catechesis for Eucharist, please see Religious Education page for Children preparing for First Communion and RCIA page for Adults preparing for First Communion.

"...Continued catechesis is given yearly in all catechetical programs for children, in as much as the sacraments require lifelong participation and study" (NCD #122).
