At a Jesuit hacienda, a peasant who failed to attend Mass might be lashed; but the average hacienda was lenient about attendance. At evening Mass after a day's labor, the workers were glad to kneel or squat: the hour was a humble reward. Hymns were sung. Someone played the organ or piano.

Each chapel or church boasted an altar—a lace-covered table with paper flowers or a rococo gilded carving, with santos (saints) and angels in the gray niches. The Virgin or saint was the focal point. Stained-glass and onyx windows appeared in the eighteenth and nineteenth centuries. Marble and onyx sometimes replaced mesquite or tiled floors. Some chapels and churches had pews, but in those without furniture the workers knelt. As for the hacienda family, they sat on cane chairs or worshipped behind a screened coro. There was a clear distance between them and the "unwashed."

Most services were conducted in Latin, a language disliked by the Indians because they considered it an affront to their integrity. Spanish was a tribulation and Latin was another. When they memorized songs in Latin or Spanish, they often mispronounced words intentionally.
