Roman Catholicism does have and allows and sanctions the nonsense of the apparitions claiming to be Mary and the non-Scriptural statements they've made. This has already been shown to you numerous times regarding the apparitions.
*****************
The apparition claiming to be Mary who gave the scapular with the promise "anyone dying in this habit shall not suffer eternal fire."
A prayer offered while holding the Scapular is as perfect as a prayer can be. It is especially in time of temptation that we need the powerful intercession of God’s Mother. The evil spirit is utterly powerless when the wearer of a scapular faces temptation, calling upon the Holy Virgin in this silent devotion.
True devotion to the Blessed Virgin Mary consists in three things: VENERATION, CONFIDENCE AND LOVE.
By simply wearing the Scapular, we can tell her every moment of the day that we venerate her, love her and trust in her protection.The Blessed Virgin of Mount Carmel has promised to save those who wear the scapular from the fires of hell; She will also shorten their stay in purgatory if they should pass from this world still owing some debt of punishment.

Right there are four lies that are contradiction of Scripture.
NO WHERE in Scripture is a promise ever made that wearing a man-made piece of cloth can save you from the eternal fire. NO WHERE. To believe that is idolatry and a departure from the faith. A number of your fellow Roman Catholics on these threads have admitted to falling for this lie. I hope you're not one of them.
Only faith in Christ and Christ alone can save you....nothing else.
NO WHERE in Scripture are we to "venerate" or have "devotion" to Mary.
We are to love the Lord God with all of our heart, soul, mind and body.
NO WHERE in Scripture does it teach that holding an idol like the scapular is a "perfect prayer" or that it is what we are to appeal to in times of spiritual warfare. NO WHERE.
Jesus taught the disciples how to pray with the Lord's prayer as a model. I guess He left out something.
Paul, in Ephesians 6 gave us the things to do in spiritual warfare....which is daily.
NO WHERE in Scripture are we ever directed to appeal to Mary in matters of prayer or anything else for that matter.

We can examine the apparitions at Fatima, Guadalupe, etc and we will find lies mixed in with some truth.
The apparitions stand in contradiction to Scripture, yet Roman Catholicism sanctions and allows these lies to be believed.
You may have noticed controversy about the Medjugorje phenomenon. Pope Francis has given the green light for Catholics to organize pilgrimages to Medjugorje, a site of alleged Marian apparitions, though the Church has not yet given a verdict on the apparitions’ authenticity.
This is an incoherent stance in which Pope Francis (as usual) manages to be self-contradictory and ambiguous. This is in example of what has repeatedly shown him to be incompetent as a teacher: a very worrying development.
As for the intercessory role of saints in heaven, that is an aspect of the efficacy of the prayers of ALL the saints, in heaven as well as on earth, as all are members of the Body of CHrist, Who alone gives every grace and benefit.
This is solidly grounded in New Testament Apostolic doctrine about (1) the efficacy of prayer and (2) the Body of Christ.
You can say you don't believe in the efficacy of the prayers of saintly men and women, no matter whether they be in heaven or on earth --- but this conclusion is not required by Scripture. Rather, I would say, it is incompatible with it, inasmuch as it denies he ongoing spiritual significance of the Body of Christ.
