Yup, way too addictive!
Actually, when the Priest announces the reading, or the lector for that matter, they don’t announce the Chapter/Verse, just the book being read from, so you didn’t miss anything. That they read from Acts means they were following the standard readings, and didn’t vary at your parish for the St.'s day.
It’s a box which can be found in a fine metal or sometimes it has a glass front door (actually it should be glass, but I’ve seen it that way enough times, it may be at your parish). It’s where the consecrated hosts are held. This is what gives the Catholic Church that amazing presence when you walk in the door, because the Consecrated Eucharist is the actual presence of God. Isn’t that absolutely amazing! At every Mass we have the opportunity to witness the miracle of the window to time opened up to Eternity and Christ steps down to be present with us through the Eucharist. It doesn’t get much better than that, and yet he’s gentle and does it in such a subtle way that those who are not prepared for the truth can easily miss the significance of what is occurring and go about their day undisturbed.
Sorry about that, whipping my catholic vocabulary about like that on an unsuspecting stranger

Yes, Charism is a spiritual gift. The Church teaches that we each receive Charisms at baptism so we can state definitively that all the baptised have certain Charisms which are intended to build up the body of Christ. Not everyone has the same Charism(s), this is related to the economy of salvation. We are expected to work together to bring the entire world to salvation through the joint use of the Charisms we have been given. Charisms are also like super talents that are intended for the good of others, rather than for our own personal gain, and they cannot be misused because they are God given.
My class is a 2 hr drive away, so while it was still relatively early when I left for my evening course, I still only arrived with a bit of time to spare. We had a Mass before class to pray for the new Pope. It’s great that I’ve found a brand new Catholic University to attend. God is Good!
