What is the meaning of these lines in the opening of Elfen Lied?


In the opening of _Elfen Lied_ titled _Lilium_ , there are these lines:

  1. > Kyrie, fons bonitatis.

What is the meaning of "fountain of holiness"? Where they dedicating?

  2. > Kyrie, ignis divine, eleison.

Who is or what is "ignis divine"?

Are these words just air or contain some deep meaning?




To give you some context, this song is sung in Latin and "Kyrie" is the a
common prayer in Christian liturgy. "Kyrie eleison" pretty much equates to
"lord, have mercy".

If you look at [some translations](https://lyrics.az/elfen-lied/-/lilium.html)
of these lyrics we see the two lines in question roughly translated as:

> Lord, spring of goodness. Lord, heavenly fire, have mercy.

So to answer your question, this _prayer_ is a fixed expression praising the
Lord. In the Christian context, these words are not "just air" and have
[history](https://christianity.stackexchange.com/questions/40916/is-the-term-
kyrie-eleison-latin-or-greek) and
[meaning](https://en.wikipedia.org/wiki/Kyrie). In the context of _Elfen Lied_
, the connection is more tenuous.
