Confession, especially with a very orthodox confessor who isn’t afraid to tell me how serious sin is. And I like getting a tough, somewhat physical penance (fasting, say a decade of the rosary while kneeling on the wooden floor, etc. . .). And I like going to confession in the evening, while the church is nearly empty (although this is rare), and always traditional (behind the screen).
This type of “tangibility” of the sacrament of confession is very spiritually boosting for me. When one merely describes confession as reciting your sins to the priest and receiving absolution, it seems to be a merely verbal action with no actual physical feeling.
But the cramped mustiness of the confessional, hearing the door shut, kneeling on the old kneeler in there, not being able to see the priest, the silence throughout the rest of the church, and performing a demanding penance help connect the severity of my sins to the sacrament and the penance. And I do appreciate the rosary not only as a prayer and devotion, but as a penance when given, because the “tangibility” of the faith is present in feeling the beads, smelling the church, and contemplating the Eucharist or Crucifix in prayer. Blessing with holy water on the way in and out of church, at any time, is also “tangible.”
That is one thing I really love about being Catholic, is the actual tangibility of the sacraments, sacramentals, and devotions which connect us to our faith.
