It was released as lesbian, gay, bisexual and transgender people around the world celebrate "Pride Month".
The Vatican has condemned "gender theory", the notion that people should be able to choose or change their gender, as a "confused concept of freedom" not "based on the truths of existence" in an official new document.
According to Vatican News, the church's news platform, the document is intended as "an instrument to help guide Catholic contributions to the ongoing debate about human sexuality".
The text, Male and Female He Created Them, was meant to help Catholic teachers, parents, students and clergy address what the Vatican's Congregation for Catholic Education called an "educational crisis" in the field of sex education. "We should welcome the congregation's call to dialogue and listening on gender, and I hope that conversation will now begin".More news: Rays take three of four from Red Sox
It describes an "educational crisis" around gender and criticises the view that gender and sexuality can be "fluid", saying such theories are "founded on a confused concept of freedom".
Rev. James Martin, a Jesuit priest who has written extensively about how the Catholic Church can improve its outreach to the LGBT community, said: "The real-life experiences of LGBT people seem entirely absent from this document".
However, Francis would likely not disagree with the document's claims, given in 2015 he compared transgender people to nuclear weapons, saying the concept of gender identity "does not recognize the order of creation". "We do believe this is very unhelpful and I think it is hard as it denies the reality of our lives and denies the reality of what we find, especially with young people on the ground, and the work that ourselves and BeLongTo on the ground in schools for instance", she said.
She said she thinks there is still an element of confusion around gender, and a document like this will just continue to confuse people as it denies the idea that there is a spectrum of both sex and gender.More news: Kim Jong Un's half brother was Central Intelligence Agency informant
"Efforts to go beyond the constitutive male-female sexual difference, such as the ideas of "intersex" or 'transgender, ' lead to a masculinity or femininity that is ambiguous", the document stated.
"Gender is also biologically determined by genetics, hormones and brain chemistry - things not visible at birth", Mr. DeBernardo said in a statement.
However, the document claims the congregation wants to "train young people to be open and interested in the reality that surrounds them, capable of care and tenderness".
"The Church should respect and encourage this process of discovery, because it is a process by which individuals discover the wonderful way that God has created them".More news: ASUS to launch 6z, not ZenFone 6, in India on June 19
