Moral Orel Chronological Order
This is as close as I could get to the appropriate Chronological order for the series (this is not the order in which the episodes were originally aired, or the order in which Dino aired them during "44 Nights of Orel"):
The Best Christmas Ever
God's Image
Offensiveness
The Lord's Prayer
Be Fruitful and Multiply
Closeface
School Pageant
Innocence
Grounded
Trigger
Passing
Dumb
Numb
Nature (Part 1)
Alone
Nature (Part 2)
Help
Sundays
Sacrifice
Nesting
Honor
I was kind of skeptical about the placement of Closeface, but this seemed like the most logical place for it to fit in, Christina and Stephanie were introduced already and it is the last episode that isn't heavily affected by Nature. Dumb and Numb could also be moved to before Alone, supposedly. Loyalty, Love and Satan could also be included, but aren't necessary.
Essentially it goes Christmas One > Arm's-length Dance > School Pageant Saga > Nature build-up > Nature > Aftermath > Christmas Two
