This question interests me in that it is so very difficult to answer. Being Catholic can mean living in any country, any culture and anywhere in the world. The answer could take a lifetime to explain and your personal answer would still be unique. So I think I might start answering it one aspect at a time. Today’s answer: Living a Catholic life means following the precepts of the Church.
The precepts of the Church:
While the Church doesn’t lay down a firm “one-size-fits-all” mentality for being Catholic but the catechism has distill the most important elements into a short list called the Precepts of the Church:
3. You shall receive the sacrament of the Eucharist at least during the Easter season.
5. You shall help to provide for the needs of the Church.
Now of course this isn’t an all encompassing list of what Catholic should do. It is just the short list, the absolute minimum that one should doing.
