Abstract
Since Pope Franziskus, there is an approach between Protestant and Catholic theology exactly in the gaze on sexual-ethical questions. However, this “new” proximity stands in continuity with the Catholic thinking, because it is not simply about the appeal on a purely subjective and quite private conscience in the positions of Pope Franziskus and of renewed moral-theological teachings. Also Protestant theology always has faced fidelity in love and partnership under God’s assistance - within all human fragility and limitedness. More clearly than it, however, the theology in Catholic tradition has described exactly this solidity of Christian experience in the modes of obligation and objective bonding. Freedom and personal responsibility must be evaluated in many areas of modern society in a new manner today. In the ecological ethics the self-linkage to standards is discussed, which orientate the own lifestyle on the natural balance for to safeguard human life in community with the nature, for example. In the formation of love and family, it needs the freely approved relationship at objective social and biographical contexts, which enable succeeding relationship basically.
