Every mass, and indeed every time we pray the rosary we recite the Creed. The word comes from Credo, Latin for "I believe" since Catholics have no imagination and name prayers and documents after the first words (e.g. the "Our Father" or "Glory Be"). The text of the prayer is as follows:
I believe in God, the Father Almighty, Creator of heaven and earth, and in Jesus Christ, His only Son, our Lord, who was conceived by the Holy Spirit, born of the Virgin Mary, suffered under Pontius Pilate, was crucified, died and was buried; He descended into hell; on the third day He rose again from the dead; He ascended into heaven, and is seated at the right hand of God the Father Almighty; from there He will come to judge the living and the dead. I believe in the Holy Spirit, the Holy Catholic Church, the communion of Saints, the forgiveness of sins, the resurrection of the body, and life everlasting. Amen
Here's my problem with that (you knew I'd complain about something). Immediately after praying this we go out into the world and make statements like "Trump is the best (or worst) president EVAH!" We say "masks don't (or do) work!" We say "Climate change is a hoax (or the most important problem of our day)!"
The thing is all of those statements are things we believe, but we don't say "I believe" these things, we state them as matters of fact, because we are so convinced of them that in our minds they surpass belief, and anyone who doesn't see this in the same light is clearly WRONG!
So why is our expression of beliefs on politics, or science, so strong compared to our belief in God? You could say that it's just the way people express themselves today, and that's a fair point, but as we speak so we think (or vice versa). In my reckoning, if our belief in God is absolute (and it should be, as God is evident from reason alone), why not express it that way?
God, the Father Almighty, is the Creator of heaven and earth, and Jesus Christ, His only Son, our Lord, was conceived by the Holy Spirit, born of the Virgin Mary, suffered under Pontius Pilate, was crucified, died and was buried; He descended into hell; on the third day He rose again from the dead; He ascended into heaven, and is seated at the right hand of God the Father Almighty; from there He will come to judge the living and the dead. The Holy Spirit, the Holy Catholic Church, the communion of Saints, the forgiveness of sins, the resurrection of the body, and life everlasting are all true. Amen
