The Holy Father made this comment today when receiving the members of the Ordinary Council of the General Secretariat of the Synod of Bishops, gathered to prepare for the synod.
The synod, to be held Oct. 5-26 in the Vatican, will reflect on the theme chosen by Benedict XVI: "The Word of God in the Life and Mission of the Church."
The Pope told the council's members that "spiritual action, which expresses and nourishes the life and mission of the Church, is based necessarily on the word of God."
"The latter, moreover, being directed to all the Lord's disciples, as the Week of Prayer for Christian Unity has reminded us, calls for special veneration and obedience, so that it will also be received as an urgent call to full communion among believers in Christ," said the Pontiff.
The Holy Father revealed that the "lineamenta," or guidelines, will be published soon.
"I am convinced that when the 'lineamenta' are published they will serve as a precious instrument so that the whole Church can reflect further on the theme of the next synodal assembly," said the Bishop of Rome.
"It is my heartfelt hope that this will help to rediscover the importance of the word of God in the life of every Christian," as well as "the missionary dynamism which is intrinsic to the word of God."
The guidelines, accompanied by a questionnaire, will be sent to episcopal conferences, the synods of the Eastern Catholic Churches, organizations of the Roman Curia, and the heads of religious orders.
The responses will be used to write the synod's "instrumentum laboris," or working document.
This will be the second synod of the world's bishops presided over by Benedict XVI. In October 2005 he presided over the synod on the Eucharist.
