Cardinal Jozef Tomko died early Monday morning in Rome at the age of 98. At the time of his death, the Slovakian-born cardinal was the world’s oldest living member of the College of Cardinals.

Cardinal Tomko died at 5:00 a.m. Aug. 8 in his apartment, where he was under the care of a dedicated nurse after hospitalization on June 25 for a cervical spine injury, according to Vatican News. He had returned home from Rome’s Gemelli Hospital on Aug. 6.

The Slovak bishops’ conference invited people to pray for Cardinal Tomko in a message announcing his death on Aug. 8.

The conference said more information about the cardinal’s funeral in Rome and his burial at St. Elizabeth Cathedral in Košice, Slovakia, will be announced soon.

Cardinal Tomko was a member of the College of Cardinals for over 37 years after St. Pope John Paul II made him a cardinal in the consistory of May 1985.

A confidant of John Paul II, Cardinal Tomko had been secretary general of the Synod of Bishops for almost six years at the time he was created cardinal.

Two days later, on May 27, 1985, he was named prefect of the Congregation for the Evangelization of Peoples. He served in that position until his retirement in 2001 at the age of 77.

For the following six years, Cardinal Tomko served as president of the Pontifical Committee for International Eucharistic Congresses. In this position, he attended several international events as Vatican envoy.

Cardinal Tomko was born in the small village of Udavské, Czechoslovakia, in the northeast part of what is now known as Slovakia.

After beginning his studies for the priesthood in Bratislava in 1943, he was sent to study at the Pontifical Lateran University and Pontifical Gregorian University in Rome, from which he received doctorates in theology, canon law, and social sciences.

He was ordained a priest in the Archbasilica of St. John Lateran in Rome in 1949. As a priest, he continued his studies, did pastoral work, and later served as vice rector and rector of the Pontifical College Nepomucenum, a theological seminary for Czech men.

Father Tomko was also co-founder of the Slovak Institute of Saints Cyril and Methodius in Rome.

From 1962 he served as an assistant in the doctrinal office of the Congregation for the Doctrine of the Faith. He headed the same office from 1966. During that time, he was chosen as one of the special secretaries for the first synodal assembly of 1967.

He was appointed under-secretary of the Congregation for Bishops at the end of 1974.

After naming Father Tomko secretary general of the Synod of Bishops, John Paul II consecrated him a bishop in the Vatican’s Sistine Chapel on Sept. 15, 1979.

In the 1980s, the Slovak prepared and oversaw three ordinary general synods, a particular synod of the bishops of the Netherlands, and an extraordinary synod on the 20th anniversary of the closing of the Second Vatican Council.

Cardinal Tomko was also active in the area of ecumenism on an international level.
