Some people say that if you go too far with money, power, food, gambling or any other thing can lead to idolatry. CCC 2113 on idolatry says " man commits adultery when he honors and Revere’s a creature in the place of God, weather this be god or demons ( for example, satanism) power, pleasure, race, ancestors, the state, money, etc. Jesus says, you cannot serve God and mammon.
Now if you’re clergy in church giving a homily and you or psyched up about the NFL while giving a homily. Who is really coming first? I don’t know the heart of that deacon but it can lead to a slippery slope if we have things like this in the church. Next thing Halloween and everybody will dress up in their favorite costumes and attend Mass.
We need to remember that this is God’s house!
God bless
