Hey Haruo.
No, i am not familiar with the Lima liturgy yet, but will have a look on it, thank you!
One thought of mine: When you say it`s popular/was used in Christian Esperanto Movement, one can find a reason in the language.
The language, as far as i know, has a great influence on people`s way to think and on culture, it is connected to certain cultures.
English is more connected to the "western world" and while there could be certainly a native american of Alasca speaking Chinese, peopele connecting that language to China and chinese culture.
It is similar in religious matters. When the (first) missionaries went to other countries from Europe, they had to deal for example with the problem that there were simply no words for some detailed parts of the gospel or the Old Testament.
So they had to translate.
And in the christian "homecountries", the language widely defined how people thought and think about christian believes. Or believes in general.
When more and more people were able to read, they were able to build there own thoughts and statements.
Esperanto maybe is not that a new language anymore, but new enough to provide a connecting base for different denominations. And it`s developing.
So i could imagine, that people in such a movement are more open to ecumenism, as you said.
Well, as i said before, "on the streets" it does not matter so much in most (western) places if one is catholic or baptist or a member of a pentecostal church. In daily life, we are humans and children of god at first and in my opinion he asks us to have respect and love for his other children as far as possible.
That does not mean to be completely indifferent, some practices in so-called "christian churches" hardly work with christian core values we learn in the bible and from Jesus.
But it would be my wish that the "real" christian communities in the world don`t look so much for what is deviding them (can one say that or is it "wrong english"?
) but for what is connecting them.
Christianity for me, among other values, is not so much about separating from other humans but about connecting and integrating.
