Parallelism is a figure of speech in which two or more elements of a sentence (or series of sentences) have the same grammatical structure.
The lines "Fondly do we hope--fervently do we pray" and "With malice toward none; with charity for all" clearly show the repetition of similar grammatical constructions.
<em>Because the speaker is using "I, we, us, or me" in the poem or is putting himself/herself in the story and whenever he/she mentions himself, he/she uses "I, we, us, or me."</em>
