As he takes the reins of the Church, he said its "number one priority" today remains preaching the Gospel of Jesus Christ in the world.
Amid the pattern of secularization in Europe, they must protect the "great treasure" of the faith in the Ukraine, he said. "We must not only not lose it, but develop it, to transmit it to the new generation."
"Inculturation" is also a vital issue for the Ukrainian Greek Catholics dispersed worldwide, he explained. "(It) means sinking the Christian values and our tradition into today's culture. This inculturation is a very important instrument of evangelization."
Full translations of the liturgical texts are still needed in many nations where the Ukrainian Catholic Church is active.
He observed a further need for the Church to be more active in providing Ukrainians with social services. He called it an "instrument" and a fundamental part of the evangelization of a society still rebuilding from communism.
The nation, he said, "is asking for this type of witness."
He also sees ecumenism as an important issue for the evangelization of society.
There has been great interest from the Orthodox Church in the Ukraine as well as from Moscow in his election. In the days before he was chosen, he spoke with other Catholic and Orthodox leaders of a building a "strategic alliance for a harmonious and single testimony from Christians" which he thinks will help to evangelize Ukrainian culture.
"There is interest, a concrete proposal, and on my part we are moving ahead to collaborate in this ecumenical, Christian and evangelizing perspective," he said.
Through open and fraternal dialogue, the ecumenical work continues to seek solutions "to all of the problems that we have received as an inheritance of the history of our nation," he said.
The new major archbishop said he has taken notes from Pope John Paul II in this realm. Through personal relationships, all walls, prejudices and divisions fall, he said.

Catholics and Orthodox Christians are not against each other, but "together," he emphasized. "We are present to bear witness to the our same faith."
If they concentrate on what unites them and not what divides, "all the prejudices and fears will disappear," he said. He also spoke of a "symphony of the traditions" between Latin and Byzantine Rite Catholics.
Referring to the future, he quoted the Ukrainian expression, "The youth is our hope." This, he said, is true in the Church and in political life.
He places great hope in a new generation of young, capable Ukrainian politicians with whom the Church can build constructive relationships for a better future.
Archbishop Sviatoslav said that for now, he will be returning to the Ukraine confirmed in the faith and supported by the rock of St. Peter. "This," he said, "gives me great courage to move ahead."
