Regarding the moral liceity of homosexual acts, Flannery was asked to submit to the proposition that "Since the homosexual practices are contrary to the natural law and do not proceed from a genuine affective and sexual complementarity, they are not approved by the moral teaching of the Catholic Church." This was supported by a quotation from the Catechism of the Catholic Church.
The priest was also asked to assent to the proposition that "The marriage covenant, by which a man and a woman form with each other an intimate communion of life and love, has been founded and endowed with its own special laws by the Creator (CCC 1660). Other forms of union do not correspond to God's plan for marriage and family. Therefore, they are not allowed by the Catholic Church."
This proposition on marriage was supported by the Catechism of the Catholic Church and by Amoris laetitia, Pope Francis' 2016 apostolic exhortation.
Finally, Flannery was invited to submit to the proposition that "In so far as it contradicts the foundations of a genuine Christian anthropology, gender theory is not accepted by Catholic teaching," supported by the Congregation for Catholic Education's 2019 document "Male and female he created them."
In a response to the CDF letter published on his website Sept. 17, Flannery wrote: "From the first moment it came to me I knew that I was not going to sign it. But it has been sitting there for the last three months or so. Now it is gone, my decision has been finally made certain and clear, and there is a sense of relief and satisfaction about that."
Speaking at a press conference on the CDF's new document on euthanasia, Ladaria said: "This is a very unpleasant situation to the congregation, very unpleasant. But it is our responsibility, and it would be an error on our part if we did not bear this responsibility and left it to one side and did not give a word, when, in certain moments, sadly, many times it should be given."
