One is supposed to be submerged in belief

One is supposed to be submerged in belief 
Somehow by a miracle 
And from then on to swim in it 
As in the least ambiguous of elements 
And even just a glance towards land 
The thought that one perhaps might be there for something else as well as swimming 
Even the slightest impulse of our amphibious nature is sin! 
What they want is an eternal song over the waves in which reason has drowned
