He said victims of abuse in Ireland were people who found themselves placed in the care of the church to be loved and respected but who so often encountered extraordinary harshness.

“When you add up all the categories of victims, you can see that the number was immense. We still only know the identity of some. It is not something that belongs to the past but a hurt that survivors and those close to them carry in their hearts every day of their lives”, he said.

He added: “The anger is not just about abuse but also about a church that was authoritarian, harsh, autocratic and self-protecting. We experienced a church that felt that it knew all the answers”.

He described Pope Francis as a kind man who inspires and touches hearts and expressed confidence that the Irish people will extend a kind welcome to him.

Dr Martin cautioned that the pontiff is not going to be able to provide all the answers to the questions people ask, adding that he hoped he will speak kindly but also frankly during his visit.

He recalled that the recent history of the church has had its moments of darkness, adding that a church of light was needed that exposes darkness for what it is and that is such that the mechanisms of cover-up and self-justification cannot extinguish.

“My hope is that Pope Francis will challenge the church in Ireland to be different, to be more authentically the church of Jesus Christ in a culture that is different”, Dr Martin said.
