Do you care about the Pope's declarations?

No.  To the extent that he supports good, I support him.

To the extent that he espouses evil, I oppose him.

no he is just a dirty old man who is rich and the people who give him money are very poor.  He needs to give his riches to the poor.

To some degree

because I like to see the quality of things - especially moral teachings - that the Roman Catholic Church is teaching its members.

They are, after all, more than half of all Christians.

(By "quality" I mean: how well it agrees with the Bible, and how well it corresponds to moral philosophy.)

As far as moral teachings go

I've VERY rarely been disappointed by any Pope's statements.

IMO

one of THE most impressive things about the Roman Catholic Church

is that it "sticks to its guns" with regard to moral teachings

though many other large Christian denominations have failed to do so

though by "sticking to their guns" it is certain that they are failing to agree with popular cultural morals (i.e. they are willing to lose members for the sake of purity of moral teaching) and suffering other difficulties (such as: desperate shortage of priests in many nations).

Sure, he is the religious leader of nearly 2 billion Catholics. Lot's of people care about what he has to say.

i DO NOT track his doings but he is a nice man.

Of course not.  I'm not a brainwashed, superstitious nut job who needs to be told how to behave.
