A celebrating priest leads a Latin Mass at Rome's ancient Pantheon basilica, in Rome, Italy, Friday, Oct. 29, 2021. Traditionalist Catholics descended on Rome on Friday for their annual pilgrimage, hoping to show the vibrancy of their community after Pope Francis issued a crackdown on the spread of the Latin Mass that many took as an attack on the ancient rite. An evening vespers service at Rome's ancient Pantheon basilica, the first event of the three-day pilgrimage, was so full that ushers had to add two rows of chairs to accommodate the faithful. Many young families, couples and priests filled the pews, hailing from the U.S., France, Spain and beyond. (AP Photo/Luca Bruno)
