Celibacy is not a matter of compulsion. Someone is accepted as a priest only when he does it of his own accord.
Pope Benedict XVILiberty isn't liberalism, arbitrariness, but it's connected; it's conditioned by the great values of love and solidarity and in general by the good.
Pope Benedict XVIBeing missionaries means loving God with all one's heart, even to the point, if necessary, of dying for him... Being missionaries means stooping down to the needs of all, like the Good Samaritan, especially those of the poorest and most destitute people.
Pope Benedict XVIThe Church must never be satisfied with the ranks of those whom she has reached at a certain point or say that others are fine as they are: Muslims, Hindus and so forth. The Church can never retreat comfortably to within the limits of her own environment. She is charged with universal solicitude; she must be concerned with and for one and all... We must... as the Lord says - go out ever anew 'to the highways and hedges' (Luke 14:23), to deliver God's invitation to his banquet also to those who have so far heard nothing or have not been stirred within.
Pope Benedict XVIRespecting the environment does not mean considering material or animal nature more important than man. Rather, it means not selfishly considering nature to be at the complete disposal of our own interests, for future generations also have the right to reap its benefits and to exhibit towards nature the same responsible freedom that we claim for ourselves. Nor must we overlook the poor, who are excluded in many cases from the goods of creation destined for all.
