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.
