|I like this poem because it's so "poemy." A lot of times people write poems and they're just "prose in stanzas that rhyme," but you have taken the time to add a poetic twist and there's a certain overall character that speaks to your personality.
I always try to date your poems, and in the first stanza it has the word "core." When I think of that word, I think of computer cores, because that's the realm that I'm most familiar with, but in actuality the word could denote any time. And truly this poem could be from any time.
I didn't understand "no eye he thus displays" except to think that maybe his eyes aren't visible. But it wasn't a deal breaker for me.
When I read the second stanza, I could see the Christian influence. "[L]ife that may yet be" could be a reference to the birth of the baby Jesus. And I couldn't figure out why you put "me" in quotes, except that maybe you were quoting the bible. On a side note, I like how you've added the "hath, speaks, shows, gives" to each stanza. It makes it easier to read, and more enjoyable.
In the third stanza, you used the word "knows" and that is interesting, because when we studied the bible, in many cases to "know" meant to have sex with. I know it's an obscure reference, but that's what I kept thinking about.
This is going to seem quite odd, but in the fourth stanza I would've put "While self may yet increase." I understand that it's a Christian thing to say that "let me decrease so that He may increase," But I tend to think that if you help others, you increase your own potential as a human being. Your spiritual power grows. Just a slight point of contention.
It was really masterful how you put "if...if...is" in the beginning of the next three stanzas. It's repetition without stagnation. I assume that in the sixth stanza you were saying that Santa Clause was "the source of Joy or Sad." That's probably an oversimplification, though.
In stanza you're saying that we should become daily Santa Clauses, sort of like how to the bible says "I die daily." Interesting. I think in stanza 8 you're saying that things get worse, even though you thought you'd suffered enough.
Was the 9th stanza about the 2016 election? Sorry I went there. Are you saying that Trump stole Christmas?
