Text in German / From a Christian perspective, complete wellness is available for man. This fact is based on God's unconditional Agape-love bestowed on man in Jesus Christ. It is by this love that being is offered a perfect vision of eternal existence. The Bible clearly shows that even creation was brought forth by the very word in which the love of the creator manifested itself in a mighty way. All being is being in the love of God, apart from which it will cease to exist. It would therefore seem advisable to examine Agape as a basic ontological category, which is our intention in this treatise. Following the course of salvation history we shall demonstrate how the love of God is responsible for being in all its complexity, where the separate parts work together constructively, thus glorifying their creator. In this way we behold the order of being in Agape. We move our attention beyond salvation of the individual but rather focus on the community aspect of salvation, and thus demonstrate from a biblical point of view, the significance of the New Testament ecclesia as the spearhead of God's Kingdom. We will show that it is the intention of Agape to give a specific Christian character to the community of believers as a witness to a world which is lacking in love and therefore also without proper orientation in its being. Where the ecclesia has lost its trait of love, we advise an uncompromising return to a corrective gospel as designed by the creator for true being, keeping in mind the limits, which the church has been given as an existing body in this world. What must never leave our focus, however, is that we extend to each other the forgiveness of Christ as the core of God's love, thus holding on to the distinct difference between Christian and non-Christian being. We therefore also recommend to examine the denominational structure of Christianity whether it is in conflict with a being that carries the mark of God's love. We remind that Agape wants to cause unity in a concrete way - unity that cannot be brought about by any secular strategy, but only by the power of God. By reorganizing our personal as well as our ecclesiastical being, the love of God will also verify the truth of God completely. / Systematic Theology and Theological Ethics / D.Th.
