When asked to explain the Catholic theology to those who have never bothered to read the Catechism I find it easier to post the Catechism. It is so well written that any attempt to paraphrase or reduce it degrades it.
The thinking has been done. No independent thought is necessary. Boy being a Latin Rite Cathiolic is easy. You are told exactly what to beieve and you just believe it. If you are confronted with a difficult question just copy and paste the official answer. Doctrinal talking points.
