Liturgy Training Publications is a premier publisher of liturgical and pastoral materials in English and Spanish. Established by the Archdiocese of Chicago in 1964, LTP promotes the liturgical formation of the faithful called for by the Constitution on the Sacred Liturgy of the Second Vatican Council. Dedicated to developing resources for the assembly, clergy, liturgical ministers, and all who study the liturgy, LTP produces books, videos, workshops, and other training materials so all the faithful may “become thoroughly imbued with the spirit and power of the liturgy” (SC, 14). Our mission is to promote the liturgical formation “of the faithful and also their active participation in the liturgy both internally and externally, taking into account their age and condition, their way of life, and their stage of religious development” so all the faithful may “become thoroughly imbued with the spirit and power of the liturgy.” (Constitution on the Sacred Liturgy 19, 14)
