The Presbyterian Church in Ireland (PCI) is in a “shameful” position, according to an internal report drawn up in the wake of safeguarding failings.

A senior church committee has recommended a review of “governance, culture and integrity issues” as well as safeguarding.

The report and its proposals will be debated by Presbyterian ministers and elders at a special meeting in Belfast on Thursday of the church’s decision-making General Assembly.

The Police Service of Northern Ireland (PSNI) announced last month it was launching a criminal investigation into safeguarding concerns within the church.

The special meeting on Thursday will be public and live-streamed online, however in a letter to ministers, there is a warning to anyone who intends to speak.

“It is important that nothing is said that would either potentially defame an individual, nor impinge upon the police investigation which is ongoing,” stated the letter, signed by two senior members of the church.

Ahead of the meeting, the Church has drawn up a 23-page report and it has been published on its website.

In a stark assessment, the report states: “In addition to safeguarding issues, there is an awareness that there are other significant matters that demand consideration by PCI which may not fall under criminal charges but involve governance, culture and integrity issues.

“This is a shameful position for part of the Church of Jesus Christ to be in.”

A number of proposals are outlined, including:

• creation of a new safeguarding department
• an independent, external review of safeguarding
• review of the use of non-disclosure agreements
• a task group to look at governance, culture and integrity

Traditionally, the two most senior permanent posts in the church, general secretary and clerk of the General Assembly, are filled by the same person. The report suggests the possibility of splitting the roles.

The Rev Trevor Gribben held the two posts for 11 years until he became the leader of the church, known as moderator, in June.

He stepped down at the end of last month in the wake of the revelations about safeguarding failures.

He said at the time: “Although not directly responsible for the professional delivery of safeguarding within the church, nonetheless serious and significant failings in our central safeguarding functions occurred partly during my tenure as general secretary.”

The previous year’s moderator, the Rev Dr Richard Murray, resumed the position at the start of this month.

At Thursday’s meeting of the General Assembly, there will be a time of worship in the morning, then lunch followed by debates in the afternoon.

Speeches will be time-limited. Proposers and seconders of resolutions will be allowed seven minutes with four minutes for other speakers.

The hall at the headquarters of the Presbyterian Church has room for about 1,000 people.

The report drawn up for the meeting says the church should “adopt a posture of a broken and contrite heart”.

It says this is a “recognition of the need for repentance, humility and lament”.

Another special meeting of the General Assembly may be held early next year, on 17 February.
