The Church is both personally and communally a religious community that God has placed together with other religions as a manifestation of the presence of God in the midst of the world.The world as a context in which the church and religions are present is a plural world. Christianity and Islam accept pluralism as an absolute part of God's actions that integrate all of His creation on the basis of mutual respect and cooperation.The uniqueness of each religion is the wealth that should be in dialogue as a strength of value that coordinate the religions themselves. The church sent into the world is a church that understands its presence as partners of God in realizing true humanitarian responsibility in building society.Therefore, the ecclesiology offered to be developed by the church is a humanistic ecclesiology, which is based on the unity of all components of society including religions in a unity that respects each other and cooperates in harmony and peace.

Humans need support in the sustainability of their lives. The surrounding natural environment plays an important role for that. If nature is damaged, and so will the human life. For this reason, we need ways to survive as well as the thoughts that underlie the way of survival.The viewpoint of Christian ethics is one of the thoughts that can be given to add insight into human thinking, especially the Christian community on the coastel waters of Inner Ambon Bay (TAD) to realize the right lifestyle with nature.This study seeks to present the contribution of ecological theology thinking to the coastal societies in Inner Ambon Bay (TAD) so that they can renew ecological behavior in order to realize the welfare of living side by side with nature biblically.
