Medalius is an independent, lay initiative with no official ties to the Church. Answers are written based on the study done so far, citing sources (the Catechism, Scripture, the Magisterium, among others) whenever possible — they may evolve and contain inaccuracies. They are a summary for study and formation; they do not speak in the name of the Church, nor do they replace the guidance of a priest. No answer intends to offend any person, belief or religion. When in doubt, consult your parish priest.
