A spokesperson for the Catholic Diocese of Waterford and Lismore has declined to comment or give any information on the visit of a controversial Catholic US speaker to address school students in the diocese later this week.
Jason Evert, who has stated that both homosexuality and the use of contraceptives is "disordered", is due to visit Dublin and Waterford and deliver talks to school students and others on Wednesday and Thursday.
Mr Evert advocates chastity for teenagers and young people who are not in heterosexual marriages.
Several planned talks appear to have been cancelled, after controversy arose on social media about Mr Evert's visit.
The cancellations included one event that was due to take place at the Tower hotel in Waterford. The talk was due to be delivered during school hours, at 10am, and was titled "Love or lust? (Catholic coed grades)".
A spokesperson for the Bishop of Waterford and Lismore said he had no comment to make when asked whether that event was now due to take place at a pastoral centre run by the diocese.
Fr Liam Power, who is head of the Diocese’s communications office, also said he had no comment to make when asked if the diocese was supporting any meetings for school students involving Mr Evert.
When asked would Mr Evert be speaking at any events organised by the diocese, Fr Power also responded with "no comment".
When asked would he give any factual information at all related to the matter, Fr Power said he had no comment.
The administrator of St John’s Pastoral Centre, who declined to be named, said she was not aware of any such meeting taking place at the centre.
On Friday, the Dublin boys fee-charging school, Blackrock College, said that a talk by Mr Evert listed on a US website was not taking place.
On Friday, the Tower Hotel meeting was advertised on the website of the Waterford and Lismore diocese.
However that listing now appears to have been removed.
It stated that "Jason is an experienced, dynamic, international youth speaker" and the event is "not to be missed".
In a book aimed at promoting chastity among boys and young men, Mr Evert writes about homosexuality: "A guy who has these attractions may not want them, or even know where they're coming from. Perhaps they stem from an unhealthy relationship with his father, an inability to relate to other guys, or even sexual abuse."
He goes on to write: "The homosexual act is disordered, much like contraceptive sex between heterosexuals. Both acts are directed against God's natural purpose for sex - babies and bonding."
On Friday, LGBT Ireland CEO Paula Fagan said such a comment was "hugely damaging and harmful to young people".
Ms Fagan said she was shocked to think that young people here could be exposed to such a claim.
On the use of condoms, which Mr Evert opposes, he writes: "Manhood is found in total self-giving, not in hiding behind a barrier. Wait until God blesses you with a bride, and then be free and unafraid to give yourself to her totally."
There are 99 primary schools and 24 post primary schools in the Diocese of Waterford and Lismore.
Asked if the Minister for Education had any comment to make on Mr Evert giving talks to school children, a Department of Education spokesperson also said they had no comment.
They referred to an earlier statement advising schools that any "outside speakers" should use "appropriate evidence-based methodologies".
