Characters: 
 1. Presumptuous, confirmed in God, Christ and Holy Spirit, figure of "man". 
 2. Malevolent, unholy figure with evil intentions - "The Tempter"; shown here not as a single person, but also like a society that lives in sin and disbelief. 
Part 1
"The Temper" urges a "Man" that all he lives for is a transparent lie and that he professes false moral [bad word]  saying that without any divine support he will be unable to resist any desires "of the world, the flesh and the devil". Nevertheless, he is fully confident in his belonging to something celestial and immaculate. 
Part 2
Years passed; "Man" gets old and realizes that "The Tempter" was right; he seeks after him, but in vain. "Man" gives up at last. He is begging "The Tempter" to alter him, and finally, to release. He realizes that the only one who can do this is, in fact, himself. 
Part 3 
Desperate, hopeless, with a foreboding of a tragic consequence, "Man" departs. He abandons his habitat, his paternal home that put him on the "straight and narrow"; with a promise that he will never revert.
