What is the overall tone of the story?

Within the improbable narrative framework, the tone of the
story takes on a wry and amusing absurdest quality. The most absurd thing is that the
angel fails to complete his task of carrying the soul of the sick infant to heaven, but
falls in the mud instead (paragraphs 1–3). Especially comic is Father Gonzaga, who
pompously preaches about the wiles of the devil, and who grows suspicious about the
authenticity of the angel because he does not understand Latin. Because Gonzaga declares
that Latin is “the language of God” (paragraph 5), he concludes that the Angel has never
been in Heaven and therefore is an impostor. Another comic thing involving the Father
the Byzantine procedure he describes for securing a Papal pronouncement about the nature
of the angel (paragraph 5).
