“The presentation of the Gospel message is not an optional contribution for the Church. It is the duty incumbent on her by the command of the Lord Jesus, so that people can believe and be saved. This message is indeed necessary.
It is unique.
It cannot be replaced.
It does not permit either indifference, syncretism or accommodation.
It is a question of people’s salvation.
It is the beauty of the Revelation that it represents.
It brings with it a wisdom that is not of this world.
It is able to stir up by itself faith – faith that rests on the power of God.
It is truth.”
(Paul VI, On Evangelization in the Modern World (Evangelii Nuntiandi), 4-5)
