The Church does not engage in proselytism. Instead, she grows by "attraction": just as Christ "draws all to himself" by the power of his love, culminating in the sacrifice of the Cross, so the Church fulfills her mission.
Pope Benedict XVIThe Church's mission is not political in nature. Her task is to open the world to the religious sense by proclaiming Christ.
Pope Benedict XVIIslam has a total organization of life that is completely different from ours; it embraces simply everything,...There is a very marked subordination of woman to man; there is a very tightly knit criminal law, indeed, a law regulating all areas of life, that is opposed to our modern ideas about society. One has to have a clear understanding that it is not simply a denomination that can be included in the free realm of a pluralistic society.
Pope Benedict XVIYou must know how to translate the indications of the word into daily witness, allowing yourselves to be formed by the word which, like seed sown in good soil, brings abundant fruit. Thus you will remain docile to the Spirit and grow in union with God, you will cultivate fraternal communion among yourselves and be ready to serve your brethren generously, especially those most in need.
Pope Benedict XVI
