Question #1: Which event created Christ's Church? Answer: Pentecost.
WRONG! This is a very common misconception. The Church has ALWAYS been in existence. The fulfillment of Christ's promises occurred at Pentecost but the church itself has always been. I can quote numerous fathers on that.
What day are the 12 Gospels read? Answer: Great Friday.
Yes, but in Parish Practice (and I think even in monastic practice; someone check me on this one) it is always done on Thursday evening though it is the Orthros for Friday morning. It's a tricky question.
In the Sacrament of Marriage, the crowns or Stephanos placed on the heads of the couple represent what? Answer:Glory and honor as king and queen of their own little kingdom, the home, which they rule with wisdom, justice, and integrity. WRONG.
Or, at least, I have NEVER heard this aetiology before. The better answer, though not the best answer is: Holiness in coming together as one. As the St. Stephen is particularly commemorated and hymns to the martyrs are chanted, the crowsn are the crowns of martyrdom as the bride and groom die to themselves for the sake of the spouse and for the sake of Christ. I have never ever heard the crowns being used to indicate a ruling over a kingdom and I've been through the marriage counseling pretty recently.
Sorry for the spoilers, but I'm the kind of person who writes in to Jeopardy! when they have stuff wrong (and believe me; they do).
