Hi, Julia1996,
OK … that’s certainly a fair question - so let me see how I can direct you on this one…
Let me use an analogy…

There is a certain collegate program (St. John’s University, I believe) that uses the Great Books of the Western World as the foundation to teach their 4-year undergraduate program. (
en.wikipedia.org/wiki/Great_Books_of_the_Western_World ) These books go back to the original ancient authors to see what they had to say about certain topics. Obviously the body of knowledge has grown - but, actually seeing how it has grown is an education in itself. These graduates are given not only a truly classical education - but, because of their teachers and reading assignments - are also knowledgeable about current items so much so that they score quite well on the Graduate Record Exam. Note, these students are not just given this classical library and told to come back in four years - rather, they are given a systematic guide through the content and then other material is provide. In brief, what you have here is an organized program of study - an intellectual disicpline to achieve a very well defined outcome: a classical education.
Now, let’s see what usually happens with contemporary religions. Someone says, “Would you like to come with me to the ________ Church. We have a great choir and the preaching by _____________ is truly inspirational!” Being… …other than “This is the True Church of God!”
To determine whether something is the true faith, all you have to go on is your personal beliefs. I guess you would have to compare the religion to what you personally believe, and see how it stacks up. I know that the truth is the truth no matter what you believe. I know that humans are capable of believing in something that is very wrong but this is the closest to reliability I can think of.
So, if you don’t use this approach, what else is available? You could… …without bias. You could … well … do a lot of work, take up a lot of your time, spend a lot of your money … and not necessarily have any valid results to show for it. Besides, how would you measure valid results, anyway?
Valid results depend on your goals. If your goal was to learn the basics of another religion, and by talking to someone of that religion you got the information you wanted, then you would have achieved your goal and obtained valid results. If your goal was to find a religion to settle down with, so that you can learn and grow, then finding that religion would be a valid result.
While the immediate answer to your question about it being beneficial to study other religions is a “yes” - just jumping in to such a topic without one being thoroughly grounded in their own Faith is both foolish and risky, You see, you are not the only one interested in such a ‘study’ …

The Devil is a real spirit with a real desire to have your damned soul to torment for all eternity! Naturally, The Evil One would never present himself in such an unflattering light - he is, after all, the Father of Lies! (John 8:44) And, when you look at all of the religions out there - here is a link to a few
religioustolerance.org/var_rel.htm how are you to know that they have been accurately presented for your consideration?
But jumping into another religion with the intention of converting would also be rewarding, provided that you picked the correct religion to convert to. You don’t know that they are being accurately presented. You assume that they are emphasizing their strong points and downplaying their weaknesses. Based on that assumption, you use human judgment to decide what you believe.
There are no easy answers on this - and for those who think such a knowledge will foster greater tolerance - I do not think this even come close to the reality we see before us today. For example, certain religions truly believe that non-believers should either convert of be killed - there is no middle ground here. By their very nature, they are quite intolerant of others. Other religions truly believe that one religion is as good as another - and we all will get to god while creating friendships on earth.
I don’t think that tolerance is going to disappear just like that. It is basic human nature to want to feel important. The easiest way to feel important is to pretend that everyone who disagrees with you is beneath you. This is where intolerance of other beliefs comes from.
The Catholic Faith for 2,000 years has demonstrated that it is quite different from these religions created by men. We have a real set of beliefs - the Nicene Creed (here is good explanation in this link:
newadvent.org/cathen/11049a.htm). A thorough searching for the truth really requires a guide - one who can point the way to Christ and the teachings of the Church. I would recommend you visit your local parish priest - tell him of your interest and seek his guidance. What you seek will really require work and a sincerity of purpose that is both mindfull of our final ends and that the Devil will do everything possible to steer you in the wrong direction.
I find it slightly amusing that another church using the same Nicene Creed can have a different interpretation of it.
What final ends do we need to be mindful of?
This is really the best advice I can give on this topic. I hope this proves helpful.
This was very helpful. Thank you.
God bless
