Trinity
I say "in the name of the Father, Son, and Holy Spirit" a lot: mostly when I start praying. I generally make the sign of the Cross at the same time. The sign of the Cross is a very "Catholic" gesture. It "reminds us in a physical way of the Paschal Mystery we celebrate: the death and Resurrection of our Savior Jesus Christ." 1 It's a prayer, a blessing, and a sacramental; and that's another topic. (Catechism of the Catholic Church, 1668 - 1670 ) Dali's " Crucifixion (Corpus Hypercubus) " is very "Catholic," too; although not it's not like the mass-produced 19th-century stuff many associate with our faith. I wouldn't be surprised if a half-millennium from now, some tight-collar Catholics will be upset by new art that doesn't present the Cross as an unfolded tesseract , and that's yet another topic .
