The body representing Christian teachers in the UK has written to Rishi Sunak to outline its concerns over a potential ban on gay conversion therapy.
The government has outlined its plans to introduce new legislation despite fears that it will stop prayer and pastoral support for someone with unwanted same-sex attraction.
Recent conflicting media reports have thrown up rumours that a ban may make its way onto the King's Speech next month.
King Charles will outline the government's plans for the forthcoming year when he visits Parliament.
The Association of Christian Teachers has published a letter it sent to the Prime Minister with further concerns that teachers could face criminal action for vocalising their "orthodox Christian views on sexual ethics".
Executive Office Lizzie Harewood said: "Our concern is that any legislation in this highly controversial space may inadvertently harm children and potentially criminalise teachers. ACT calls for an urgent reconsideration of whether there is a need for new legislation."
Hundreds of church leaders have signed petitions warning that they will be forced to break the law in order to give pastoral care to their members.
It's a concern shared by Harewood.
"Our members have no desire to become criminals, and as a Christian organisation, we place a high value on being law-abiding citizens.
"It is extraordinary that we find ourselves in a position where this could be jeopardised by the Government giving in to activists who are openly hostile to us because of our beliefs."
The government has said it does not comment on speculation around the King's Speech but has previously said that it would ensure that the bill did not have "unintended consequences" and would protect "legitimate conversations" and that only abusive practices would be outlawed.
