VATICAN CITY, NOV. 23, 2008 (Zenit.org).- Benedict XVI has appointed a Korean economist, Thomas Han Hong-Soon, as the Vatican's international controller for the Prefecture for the Economic Affairs of the Holy See.

As financial controller, Han will be responsible for examining the Vatican's accounts and balance sheets.

A professor of economics at the College of Business and Economics of Hankuk University of Foreign Studies in Seoul, Han is president of the Catholic Lay Apostolate Council of Korea.

He also participated as an auditor in October at the world Synod of Bishops on the Word of God, warning against inadequate management of the Church's material goods.

The professor explained that "formation in the Word of God must be 'performative'" and "must include a solid formation in the Church's social doctrine."

"In this sense, the Compendium of the Social Doctrine of the Church can be a valid instrument," he observed. "We need educators who are competent in the field of social doctrine and in the study of the Word of God."

For this reason Han said the Church "must invest human and financial resources in the formation of educators."

"A performative formation in the Word of God demands that the whole Church and all its members must bear witness with actions," the professor continued. "We must understand that people are persuaded more by holiness of life than by intellectual discussion."

In his view, the leaders of the Church "must seriously examine the Church's lifestyles and goods in the light of the Word of God and use every possible measure to promote the [Church's] social doctrine."

In the same way "in negotiating commercial contracts the Church must make sure that they contain principles of justice, sufficient pay for living and good working conditions," said Han.

"Unfortunately, in the past the Church has not always maintained a high standard," he noted.

The professor concluded his speech expressing the wish that the synod would promote "a biblical lifestyle proper to a Church that bears witness to and promotes a performative formation of lay people."
