Lead role for youth
Youth have an important role to play in the preservation of water according to Oji. The more established leaders, even within the church, often do not address these issues.
Lilit Babajanyan from Armenia added that if she wanted to do something to counterbalance the political influence of rich landowners in the fight over Armenia's Lake Sevan the best starting point for her was her personal network of friends - a group of young Christians.
When the concern for creation brings together Christians aged 20 to 30, they will of course not limit themselves to academic exercises. In between sessions they shared about their homes and cultures and taught each other songs from their home churches.
The drawings and hip-hop lyrics posted on the Ecumenical Water Network's summer blog also bear witness to their creative talents.
Creativity was one of the criteria for choosing candidates for the summer school because of its value in bringing to life powerful biblical stories about Christ's promise of justice and the "living water" of faith.
"How can Americans hold water as sacred when it is wasted away every day?" Kelly Forbush, a theology student from the United Church of Christ in the USA, wrote in a blog entry about her reflections from one of the morning Bible studies. "Water comes in such abundance in America - almost all people can receive clean water anytime they want."
One possible answer to Forbush's question came through the water-themed worship service which the summer school participants prepared for the Lutheran congregation of Geneva. With prayer, songs and acting the service created links between the biblical imagery of the "living water" and the modern day reality of many people not having access to water.
The first generation of summer school "alumni", whether they came from the privileged regions of North America and Europe, where a constant supply of clean water is taken for granted, or whether they are faced with its scarcity in their every day lives, will not forget the need for water is shared by all.
And they will not keep to themselves the realisation that consumer patterns in their own communities - concerning energy, meat, traffic and many other things - affect the water supply of people living on the other side of the globe.
As they travelled back to their home countries in early August, some already had concrete ideas about how to spread what they have learned, for example performing plays about the water crisis in public places or beverage stores. Others think about organising regional summer schools. For knowledge, just like faith, multiplies when it is shared.
