Be not afraid!
At all times, but particularly in the last two centuries, the Popes, whether individually or together with the College of Bishops, have developed and proposed a moral teaching regarding the many different spheres of human life...
Jesus Christ, the "light of the nations", shines upon the face of his Church, which he sends forth to the whole world to proclaim the Gospel to every creature (cf. Mk 16:15). Hence the Church, as the People of God among the nations, while attentive to the new challenges of history and to mankind's efforts to discover the meaning of life, offers to everyone the answer which comes from the truth about Jesus Christ and his Gospel. The Church remains deeply conscious of her "duty in every age of examining the signs of the times and interpreting them in the light of the Gospel, so that she can offer in a manner appropriate to each generation replies to the continual human questionings on the meaning of this life and the life to come and on how they are related".
The Church's Pastors, in communion with the Successor of Peter, are close to the faithful in this effort; they guide and accompany them by their authoritative teaching, finding ever new ways of speaking with love and mercy not only to believers but to all people of good will. The Second Vatican Council remains an extraordinary witness of this attitude on the part of the Church which, as an "expert in humanity", places herself at the service of every individual and of the whole world. - Introduction, Veritatis Splendor
O God, who are rich in mercy
and who willed that Saint John Paul the Second
should preside as Pope over your universal Church,
grant, we pray, that instructed by his teaching,
we may open our hearts to the saving grace of Christ,
the sole Redeemer of mankind.
Who lives and reigns with you in the unity of the Holy Spirit,
one God, for ever and ever.
