And out of cruiosity, can a person adopt catholism without being baptized and having any relationship with the church?

How do you mean mtlm? Just follow the ideas catholicm is speaking of?

 It is not ebcause I do not agree with you however these are just your claims because people who believe in religions do believe that religions are directly related with God and they are essential because they tell us to live the way God want us to live, like a life guide.

And I think religions are not institutions, but churches can be at the most.

Anyway, these days when a person ask me about my blief, I just tell him that I do not have time to think about these kind of stuff. Then they ask me if I am atheist, and I say "don´t know because first I should give a thought about it even to be an atheist.

 Forexample I decide that I want to be a catholic, do I have to be baptized?

 If you want to be a practical catholic, or as you wrote devoted - than yes, and not only baptised, after that you would have to give your best live in accordance with the rules set out in the Bible and so on.

One can be not religious and yet live a righteous life just because one is living but her/his conscience.

Maybe I have a little too opened view of mine and other religious because of the very specific life I have in my country where religion is important, but none is dominant on the state level. Some would strongly disagree with this, but one has to really become critical and sincere to her/himself in odrer not to take discussions like this one as attacks on something or someone

 A very "Christian" view and typical of many "Christians" I know

Don´t hold on to every word I write below, it´s been a long time since I went to Sunday school and read religious literature...

Maybe I memorised it wrong since any OTHER way is against my reason and sanity - Every person, baptised or not, christian or not, will be judged by her/his deeds and actions, how much good did she/he did in life, how many times choose the harder way just because that was the honest way. I believe that ALL good people will go to Heaven, so our DEEDS will be judged, not US. Hope this makes sense to someone else, not just me

You are indeed WRONG, faith has everything to do with your belief in God.  Do you even know what faith means? Part of christianity is being baptised and going to church, but you also have to follow the teachings and apply it.   If you don´t believe in God that is your choice, we all are born with free will. 

 Hahaha as I have long suspected, the main reason for religion is "fear of death" and you just confirmed it (along with Teaship).

So forget your "love of God", it is all about the paradise eh?  It is rather like marrying someone for money!

I love Azade´s phrase "let anyone in"...  how tragic to live your life under strict religious rules (not that many actually do that ) and then find out that all the sinners made it through too

Sure anyone can adopt Catholicism, however in order to be received fully into the church you have to receive three sacraments, initiation (baptism), confirmation and the Eucharist.  Once you are baptized you become a Catholic.  The other two sacraments deepens your initiation.
