And Protestants believe the very same things. Where the disagreement comes in is the statements from some Catholics who insist that works are necessary for salvation, when Scripture says they are not. The thief on the cross had absolutely NOTHING to offer, yet Christ took him to Paradise that very day. Hear me, works are necessary for the following reasons:Is obedience to Christ necessary? What did he command? Did we feed the hungry, give drink to the thirsty, clothe the naked, etc.? Did we discern the will of God and follow it? What talents were we given? How many will we return to the one who loaned them to us?
Catholics believe so wholeheartedly in Christ, his words, the way he lived, that the present life is devoted to him and his Way of obedience to the Father even unto death, that it never occurs to us that we should wait until we die and are in heaven before we follow Christ with our whole heart, whole mind, whole soul. The kingdom is here and now and continues in the afterlife. We don't have to wait for the afterlife.
"Boasting" is another mirage. Catholics remember clearly that we are not to let our left hand know what our right hand is doing. On the other hand, city lights on a hillside cannot be hidden--which may be why so many toss "earning" and "boasting" at those Kingdom/city lights. All are most welcome in this kingdom; no need to stand outside with suspicious minds.
1. To demonstrate our faith. Faith without works is dead, because faith NECESSARILY results in good works. Show me your faith without works and I'll show you my faith by my works.
2. To follow Christ's commands. He obviously commands us to make disciples, to show His love, to care for the less fortunate, all of those things.
The problem comes in when people claim they are Christians because they do good works, and ignore what Christ wants to do in their hearts, ignore what the Spirit is calling them to do, live outwardly "good" lives while continuing to revel in sin. Having a form of godliness, they deny the power thereof.
BTW, it's human nature to boast. Don't tell me that many Catholics do not feel superior to others because they do good deeds. That's why God set it up that way, so that no one can claim to be better than anyone else.
