The pontiff made the shocking disclosure as he was addressing canon lawyers at the Vatican for a course on marriage dissolution conducted by the Roman Rota, the Church’s highest court.

“We have to be careful that the procedure does not become some kind of business,” the Pope said. “There have been public scandals.

“I had to dismiss a person from a tribunal some time ago who said: ‘Give me $10,000 and I’ll take care of both the civil and ecclesiastical procedures.’ Please, not this!”

Francis did not provide any more details about where or when the sacking occurred. He stressed the need for the Church’s annulment procedures to be easier, faster and cheaper. He even suggested fees could be waived.

“When you attach economic interests to spiritual interests, it is not about God,” he said.

“The mother Church has so much generosity it could provide justice free of charge.”

Questions surrounding marriage and annulments provoked plenty of debate last month at the Vatican’s Synod on the Family as several conservative cardinals resisted moves to open Communion to divorced and remarried Catholics. Among them was American Cardinal Raymond Burke, an outspoken conservative who heads the Roman Rota. Burke, a former archbishop of St. Louis, has said publicly that he is likely to be demoted soon by Francis.

Annulments are a major issue in the Roman Catholic Church because Catholics who divorce and remarry without seeking an annulment for the previous marriage are prohibited from taking Communion. In the eyes of the Church, without an annulment their first marriages are still valid and so they are in effect committing adultery with their new spouse.

Some Catholics complain that the process of obtaining an annulment is arduous, expensive and at times capricious.

Francis spoke about the importance of fairness and accessibility to Church tribunals. He said many processes were “so long and so weighty” that many people became “discouraged” and abandoned the process altogether.

The former archbishop of Buenos Aires said some people in his home country of Argentina lived long distances from a tribunal and so could not afford to take the time from work to go to court to pursue an annulment.

The Pope also referred to the commission he established in August to study reform of the canonical matrimonial process and simpler procedures while safeguarding the “indissolubility of marriage.”
