Who are the faithful Catholics left in the world? Is pride enough to send one to Hell?

1. The faithful Catholics left in the world are those who maintain the true Faith.  2. I don't know the number of those. 3. If pride is grave then it will lead to mortal sins which will put a person in hell. And “pride is the beginning of all sin” (Ecclus. 10:15). Pride causes man not to pray as much, not to fear sin, not to listen to what they should or to whom they should, not learn what they need to know. Pride causes people to dismiss truth or people speaking the truth by finding fault with petty things. We’ve dealt with many people who, though they don’t have haughty personalities, admit that they commit mortal sins and yet they are still critical of others’ spiritual lives. Frankly, if they commit any mortal sin then they shouldn’t be criticizing anybody. But they cannot see their decrepit state because they are filled with pride: “…knowest not, that thou art wretched, and miserable, and poor, and blind, and naked.” (Apoc. 3:17) They don’t fear to offend God by their mortal sins because they are filled with pride.
