If you hold the Catholic Faith then you must believe, as Catholics do, that if a person knows the Catholic Faith is the truth and then refuses to be joined to it, he cannot be saved. Willful rejection of the known truth is a Sin against the Holy Ghost.
It is not a teaching of the Church that āall will not come to Christ and theyāre not doomed if they donātā It is rather the teaching of the Church that Jesus is the Way, the Truth, and the Life, and no one comes to the Father but by Him.
Now, there is some theological speculation about implicit vs explicit faith. Implicit Faith is viewed as an attitude of mind wherein one seeks the truth diligently, and strives with all oneās strength to live up to what one believes God wants one to do. Such a one can be saved, but with difficulty, and that one is in ignorance of the true dual Nature of Christ. Such ignorance, if it be invincible, can be excused, but it is not an ideal situation, as such a one will necessary lack very many helps that can only be received in explicit faith. For such as these, it ought always to be our aim, to bring them into explicit faith, so that they may be more easily saved and may merit a better crown.
I wouldnāt be so concerned about āselling points.ā The sole āselling pointā of anything can only be its truth; and in a secondary way to truth, its facility of application. One both these counts, the Rosary is a very important key. The Rosary is first of all a devotion specifically approved by God and recommended by Him through all His prophets and Saints. Secondly, the Rosary makes Catholicism far easier to practice faithfully. It destroys heresy and converts from sin. It is impossible to go too far in recommending the Rosary.
Now I am going to ask you for clarification, what do you mean by your phrase, above, āJesus said to the Lord. . .ā? JESUS IS LORD! That is the Faith of the Church. No one can be Catholic who does not believe that.
