There are many tenets of our Catholic faith that make us unique from other Christian denominations. The Communion of Saints, Purgatory, the Sacraments, Sacred Tradition are just a few examples. But nothing is more central to being Catholic than the Real Presence of Christ in the Eucharist. In fact, this truth is polarizing. It has been this way up and down the centuries.
I read the story of Pentecost in the second chapter of the Acts of the Apostles and I think back to my Confirmation in eighth grade. I read about the Apostles and their amazing response to the Holy Spirit. They were given the gift of courage to boldly proclaim the Gospel and they were given the gift of language so that the Gospel could be proclaimed to the Gentiles. I sometimes wonder why I did not have a similar response to the outpouring of the Spirit at my Confirmation.
