Do Catholics view other religion as a sin?

I'm interested to make this question after reading Do Catholics view atheism as a sin? , where the answer is : > Yes.
Catholicism states quite clearly that atheism is a sin. **Disbelieving > God** means that you are rebelling against God's commands and therefore > sinning. The bold word is quite difficult for me to understand, because it can raise a question *"whose God ?"*
In other words, the sentence above is the same meaning with this sentence :
> Disbelieving Jesus means that he/she is rebelling against **God's > command** and therefore sinning. But then again, it raise a question *"whose God command ?"* More complicated: > Disbelieving Jesus means that he/she is rebelling against **Jesus' > command** and therefore sinning. A person (who has a religion) doesn't believe Jesus.
So, do Catholics view other religion as a sin?
