I missed the verse about at the name of Mary every knee will bow. Same for the saint of the day....
Yes, assurance of salvation:
For you were called for freedom, brothers. But do not use this freedom as an opportunity for the flesh; rather, serve one another through love. For the whole law is fulfilled in one statement, namely, “You shall love your neighbor as yourself.” But if you go on biting and devouring one another, beware that you are not consumed by one another. I say, then: live by the Spirit and you will certainly not gratify the desire of the flesh. For the flesh has desires against the Spirit, and the Spirit against the flesh; these are opposed to each other, so that you may not do what you want. But if you are guided by the Spirit, you are not under the law. Now the works of the flesh are obvious: immorality, impurity, licentiousness, idolatry, sorcery, hatreds, rivalry, jealousy, outbursts of fury, acts of selfishness, dissensions, factions, occasions of envy, drinking bouts, orgies, and the like. I warn you, as I warned you before, that those who do such things will not inherit the kingdom of God. (Galatians 5:13-21)So much for the "assurance of salvation" for those who continue in sin. By grace alone, yes; but not without works.
What good is it, my brothers, if someone says he has faith but does not have works? Can that faith save him? If a brother or sister has nothing to wear and has no food for the day, and one of you says to them, “Go in peace, keep warm, and eat well,” but you do not give them the necessities of the body, what good is it? So also faith of itself, if it does not have works, is dead. Indeed someone may say, “You have faith and I have works.” Demonstrate your faith to me without works, and I will demonstrate my faith to you from my works. You believe that God is one. You do well. Even the demons believe that and tremble. Do you want proof, you ignoramus, that faith without works is useless? Was not Abraham our father justified by works when he offered his son Isaac upon the altar? You see that faith was active along with his works, and faith was completed by the works. Thus the scripture was fulfilled that says, “Abraham believed God, and it was credited to him as righteousness,” and he was called “the friend of God.” See how a person is justified by works and not by faith alone. And in the same way, was not Rahab the harlot also justified by works when she welcomed the messengers and sent them out by a different route? For just as a body without a spirit is dead, so also faith without works is dead. (James 2:14-26)And please, do not go quoting other scripture passages without addressing what both Paul and James state clearly here.
