The answer to your question is NO. The Sacrament of Conformation is not absolutely necessary for salvation, but if you go on neglecting something you need to live a truly holy life, you are putting yourself in grave danger, especially in the worldy environment you find yourself in.

I guess that you must not have been well catechised or you would not be asking this  question or the other question "What's the Resistance's stance on this?" You would know there cannot be different stances on the Sacraments in genuinely Catholic movements of which the Resistance is one. The Resistance holds to the Church's teaching. It's that simple.

May I suggest that you pray this: http://www.christorchaos.com/NovenatotheHolyGhost2.html

It will help you to understand the gravity of the situation and increase your understanding of the gifts of the Holy Ghost and your duties as a Catholic. Meanwhile speak with your priest ASAP.

God bless you MrYeZe.

From Trent's Catechism:


All Should Be Confirmed

First, it is necessary to teach that this Sacrament is not so necessary as to be utterly essential to salvation. Although not essential, however, it ought to be omitted by no one, but rather, on the contrary, in a matter so full of holiness through which the divine gifts are so liberally bestowed, the greater care should be taken to avoid all neglect. What God has proposed in common unto all for their sanctification, all should 'likewise most earnestly desire.

St. Luke, indeed, describing this admirable effusion of the Holy Spirit, says: And suddenly there came a sound from heaven, as of a mighty wind coming, and it filled the whole house, where they were sitting; and a little after: And they were all filled with the Holy Ghost. From these words we may understand that, as that house was a type and figure of the Church, the Sacrament of Confirmation, which tool; its beginning from that day, appertains to all the faithful.

This may also be easily inferred from the nature of the Sacrament itself. For they ought to be confirmed with the sacred chrism who have need of spiritual increase, and who are to be led to the perfection of the Christian religion. But this is, without exception, suited to all; because as nature intends that all her children should grow up and attain full maturity, although she does not always realise her wishes; so the Catholic Church, the common mother of all, earnestly desires that, in those whom she has regenerated by Baptism, the perfection of Christian manhood be completed. Now as this is accomplished through the Sacrament of mystic Unction, it is clear that Confirmation belongs alike to all the faithful.

No, it's not necessary like Baptism.
No, it's not something superfluous like a nice hat -- a situation where you can just as easily take it or leave it.

You need to get confirmed. Our Lord didn't institute any superfluous Sacraments.

As for the Resistance (since you mentioned it), I want to clarify something.

There is only ONE true religion founded by Jesus Christ. That is the Roman Catholic Church.

In the 60's the Church was infiltrated by her enemies, and a period of self-inflicted destruction began in the Church. Widespread confusion and ignorance reigned, while souls were lost and the Faith was taken away piece by piece. This is called the Crisis in the Church, and from this chaos the Traditional movement was born -- basically a bastion of the Catholic Faith.

Fast forward to 2012 -- it became publicly known that the largest Traditional group, the SSPX, was going the way of the Indult and Rome-approved (neutered) groups. History has proven that all groups that made a premature deal with Modernist (conquered) Rome became neutered as a fighting force for Catholic Tradition. Once compromised, they are of little value to anyone. The bad guys in Rome know this.

So the Resistance was born as the true successors of the SSPX (which is just part of the Traditional movement). So the Resistance is just part of the Traditional movement.

Being a Traditional Catholic is the safest way to keep your Faith. We have to keep our distance from the Modernist contagion, or we too might fall. "He who thinks himself to stand, take heed lest ye fall!" and "Pride goeth before the fall."

"I can handle it" they say -- that's pride speaking. No, we need to assume that we too are in danger, and go far, far away from Modernism and all such contagion. Modernism was designed to be poisonous to the Faith, to insinuate itself into every aspect of it, and destroy it slowly but surely.

Modernism does to the Faith what a chemical weapon does to the flesh.
