Facing the reality of a serious ecological crisis, where the complete order of the life world is not preserved but rather the symptoms of various forms of collapse are clearly witnessed, it would not be too much to say that Christian churches and believers have the responsibility to respond to these crises. Moreover, it can be said that it is a self-evident theological truth to respect the value and position of God’s created world and all beings in the world and to im- plement concretely such respect through altruistic acts for all the beings of the world. Honoring these theological ethical truths and justifications, I will respond to the ecological crisis by carrying out the task of seeking ecological love. My task here is two-fold. I will justify ecological love theologically, focusing on Gene Outka and Jürgen Moltman. Also, I will attempt to explore Outka’s and James A. Nash’s theories of ecological love and expand the horizon of ecological love through critical dialogue between the two.
