And based upon his testimony you need to start with your own tent, since as he states in Justification by Faith,
Over the past twenty-five years I have asked hundreds of Catholic college students the question: If you should die tonight and God asks you why he should let you into heaven, what would you answer? The vast majority of them simply do not know the right answer to this, the most important of all questions, the very essence of Christianity. They usually do not even mention Jesus! - https://www.catholiceducation.org/en/religion-and-philosophy/apologetics/justification-by-faith.html
Roman Catholic professor Peter Kreeft also believes that, When Luther taught that we are saved by faith alone, he meant by salvation only the initial step, justification, being put right with God. But when Trent said we are saved by good works as well as faith, they meant by salvation the whole process by which God brings us to our eternal destiny and that process includes repentance, faith, hope, and charity, the works of love. — ibid
And since Luther also clearly affirmed that it was only effectual faith that justifies, faith and works being inseparable, that faith is a living and an essential thing, which makes a new creature of man, changes his spirit... Faith cannot help doing good works constantly... if faith be true, it will break forth and bear fruit... where there is no faith there also can be no good works; and conversely, that there is no faith.. where there are no good works. Therefore faith and good works should be so closely joined together that the essence of the entire Christian life consists in both. if obedience and God's commandments do not dominate you, then the work is not right, but damnable, surely the devil's own doings, although it were even so great a work as to raise the dead... if you continue in pride and lewdness, in greed and anger, and yet talk much of faith, St. Paul will come and say, 1 Cor. 4:20, look here my dear Sir, "the kingdom of God is not in word but in power." It requires life and action, and is not brought about by mere talk. Works are necessary for salvation, but they do not cause salvation... faith casts itself on God, and breaks forth and becomes certain through its works... faith must be exercised, worked and polished; be purified by fire... it is impossible for him who believes in Christ, as a just Savior, not to love and to do good. If, however, he does not do good nor love, it is sure that faith is not present... where the works are absent, there is also no Christ... References and more by God's grace. , then the Reformation and Counter-Reformation was much that of misunderstanding?
Rather, despite the modern Cath emphasis upon faith, what the RC gospel essentially teaches is that by the grace of God one actually becomes good enough to enter Heaven/glory/God's presence. Thus as Kreeft "also stated, "...we will go to Purgatory first, and then to Heaven after we are purged of all selfishness and bad habits and character faults." - Peter Kreeft, Because God Is Real: Sixteen Questions, One Answer, p. 224
The “Catholics clean house” argument also undermines our own theology. Is the Eucharist the “source and summit of the Christian life,” as Lumen Gentium preaches, or not? If it is, how could we in good conscience not direct other Christians to its salvific power? Jesus Himself declared: “Truly, truly, I say to you, unless you eat the flesh of the Son of man and drink his blood, you have no life in you.” (John 6:53)
However, to be a faithful Catholic means to assent to the living magisterium's understanding of John 6:53, and rather than meaning that those who do not believe in the Cath Eucharist have no life in them, Lumen Gentium and other modern teaching generally affirms of properly baptized Protestants - all of which deny the Catholic Real Presence and according to Rome lack the necessary priest to confect the Eucharist - "that those who are baptized in these communities are, by Baptism, incorporated in Christ, and are "in a certain, although imperfect, communion with the Catholic Church," being "joined with us in the Holy Spirit" who "is operative among them," such as the "many who take Sacred Scripture as a norm of belief and a pattern of life" and lovingly believe in the Trinity.

Was our Lord misrepresenting the Eucharist?
Consider how much more fruitful our fight against the devastation of the sexual revolution would be if we persuaded Protestants that they need to reject things like contraception
Again, see to thine own house;
Just 15% of U.S. Catholics say that using contraceptives is morally wrong. 41% say that using contraceptives is morally acceptable, while 36% say it is not a moral issue. 37% of Catholics who attend Mass at least once a week say using contraceptives is morally wrong while 33% say it is morally acceptable and 30% say it is not a moral issue. — http://www.pewresearch.org/key-data-points/u-s-catholics-key-data-from-pew-research/#abortion
74% of Evangelicals, 73% of Mainline Protestants, and 68% of sexually active Catholics women use birth control. 3% of the Catholics rely on natural family planning. Attendance at religious services and importance of religion to daily life are largely unrelated to use of highly effective contraceptive methods. ^
88% of Catholics believe that they can practice artificial means of birth control and still be considered good Catholics. New York Times/CBS News poll, Apr. 21-23, 1994, subsample of 446 Catholics, MOE ± 5%
98% of self-identified Catholic women ages 15-44 who have ever had sexual relations have used a method of contraception other than natural family planning at some point in their lives. .” http://www.washingtonpost.com/blogs/fact-checker/post/the-claim-that-98-percent-of-catholic-women-use-contraception-a-media-foul/2012/02/16/gIQAkPeqIR_blog.html?wprss=fact-checker
40% of 18- to 29-year-old Catholics said the church’s “teachings on sexuality and birth control are out of date.” http://www.barna.org/teens-next-gen-articles/528-six-reasons-young-christians-leave-church
59% of all Catholic women of childbearing age practice contraception—a rate of usage statistically equivalent to that of the general population (60%). Calvin Goldscheider and William D. Mosher, "Patterns of Contraceptive Use in the United States:
58% of Catholics 52% if they are voters) believe that employers should be required to provide their employees with health care plans that cover contraception;
50% of white Catholics support this requirement, versus 47% who oppose it, along with 38% of white evangelical Protestants an 50% of white mainline Protestants. Public Religion Research Institute, February 2012 http://publicreligion.org/research/2012/02/january-tracking-poll-2012/
and the more permissive stance towards divorce that they have allowed to seep into their churches.
Grievously, yet so is the unscriptural redefining of marriage via a broad criteria that relegates marriages that are considered marriage in Scripture to having never taken place, resulting in thousands of marriages being "annulled." Which broad criteria potentially means that multitudes of other Catholic marriages are invalid as well.
the very nature of Protestantism has contributed to the individualism, secularism, and moral relativism of our age.
Rather, it is the demeaning of Scripture that is the problem, thus those who most strongly esteemed as the accurate and wholly inspired word of God, with its basic literal hermeneutic testify to being far more conservative and unified in polled core beliefs and values than overall those whom Rome counts as members in life and in death. Thus evangelicals have been religious enemy #1 for liberals and Catholic alike in the West.
Why bother to evangelize devout Protestants? Because
distinctive Catholic teachings are not manifest in the only wholly inspired substantive authoritative record of what the NT church believed (which is Scripture, in particular Acts through Revelation, which best shows how the NT church understood the gospels).
Also, you have not defined just who the real RCs are. For there are many RC sects, such as with many here asserting,
"Bergoglio the Heretic;"
"preaches and authors heresy;"
"the material and formal heretic;"
this fraud of a pope;
“an apostate,”
"he's not a Catholic;"
"Pope Frank..protestant;"
"The Impopester;"
"The Ecumenical Mass of Bergoglio is straight out of Hell;"
"...for which our poor, beleaguered pontiff is nothing more than the ultimate poster boy."
I would note that Protestants don’t do great in this type of polling, and there are entire mainline denominations that are dead. Even so-called evangelicals come up with scary results in opinion polling. (Barna group does a lot of it.)
There are plenty of tares among the wheat.
