NOTRE DAME, Ind.—Together for Life, the bestselling and most trusted source for wedding planning in the Catholic Church, has surpassed 10 million copies sold.

Now in its sixth edition, TFL includes all the tools engaged couples use when meeting with a priest, deacon, or lay parish minister to plan their weddings and prepare for living the sacrament of marriage. It is used to plan about 80 percent of Catholic weddings in the United States.

It was written by Msgr. Joseph Champlin (1930-2008) and first published in 1970. Rev. Peter Jarrett, C.S.C., added catechetical content to a later edition and helped update it to include the revised liturgical texts of the third edition of the Roman Missal. TFL was last updated in 2016 to include all of the necessary texts from The Order of Celebrating Matrimony.

“Msgr. Joseph Champlin’s gift to Ave Maria Press is a continued blessing to us and indeed to the Church, to the Congregation of Holy Cross, and of course to the married couples who have used the book to prepare not only for their wedding but for their marriage,” said Publisher Thomas Grady. “We don’t take this legacy for granted.”

Together for Life will celebrate its fiftieth anniversary in 2020. The material in TFL is supported by TogetherforLifeOnline.com. The booklet is also available in Spanish.

Ave Maria Press was founded by Rev. Edward Sorin, C.S.C., in 1865 and is recognized as a leader in publishing Catholic high school religion textbooks, ministry resources, and books on prayer and spirituality. Ave Maria Press is a ministry of the Congregation of Holy Cross, United States Province of Priests and Brothers.
