These are not the teachings of the Roman Catholic Church.
Officially, no.
Unofficially, the vatican has allowed homosexuality to flourish under many popes now, from the vatican now.
Sadly.
"Top Vatican official: Gay sex in Vatican ‘never been worse’ than under Francis"
From 2017
"Not only are gay-orgies happening in the Vatican, but the extent of homosexual activity in the Vatican under Pope Francis’ watch has 'never been worse,' a reliable senior member of the Curia told National Catholic Register’s Ed Pentin.Pentin wrote earlier this week that this Vatican Curia member confirmed to him that 'multiple sources' within the Vatican, including another senior curial figure, say that the report of a drug-fueled gay orgy right next to St. Peter’s is true...
He said the extent of homosexual practice in the Vatican has ‘never been worse,’...
News recently broke of a high-ranking monsignor, Luigi Capozzi, who was allegedly arrested some two months ago in the act of hosting a cocaine-fueled homosexual orgy in an apartment of the Holy Office, the same building in which the Congregation for the Doctrine of the Faith operates...
At the same time of the 2012 Vatileaks scandal — where leaked confidential Vatican correspondence allegedly revealed power struggles and intrigue at the highest levels of the Catholic church — a Polish priest released a paper in which he highlighted his discovery of what he called a 'huge homosexual underground in the Church.'
Fr. Dariusz Oko said he first began to do research about external threats to Christianity, but then gradually discovered that the 'enemy is not only outside the Church, but within it, as well.'
Oko said he uncovered homosexual cliques of clergy, even at the highest levels, that are formed by fear of exposure, lust for power, and money."
If priests like this are allowed to openly advocate these things without censure or reprimand then it is a teaching of the Roman church.
Did the teachings of the Christ instruct his ‘church’ to run inquisitions, torture or burn people alive for ‘heresy’, etc?
None of what is happening now is new. It’s always been the way of the organized church to seek power in whatever way necessary to the times.
The real Church is inside of you. You don’t need priests and popes and beautiful structures and organizations, to MAKE it real. Christ already made it real for you.
