Pope Francis made headlines this week when he officiated at the weddings of 20 couples, including some who had been living together and a woman who has a daughter from a previous relationship.
It was the first time that the Argentine pontiff had presided over a marriage ceremony since his election and it may have also signaled a dramatic shift in Catholic Church doctrine.
Now five conservative cardinals appear to be hitting back.
In a new book to be released days before the world’s Catholic bishops gather at the Vatican for their October Synod, the hard-liners are challenging moves to moderate church doctrine on marriage and offer Communion to divorced Catholics who remarry.
The book, Remaining in the Truth of Christ: Marriage and Communion in the Catholic Church, will be published in five languages, including English and Italian, on Oct. 1.
