Not according to the Apostle John who explicitly wrote, “These are written that you may believe that Jesus is the Christ, the Son of God, and that believing you may have life in His name”?
But since nobody is infallible, how do you know that's really true? How do you know the Apostle John really "explicitly wrote" it, anyway? How do you know there was an "Apostle John"? How do you "know" what "to know" means?
Reminds me of the Thirty-Nine Articles, which blithely assert that "Popes and Councils hath erred, blah, blah, blah". How do we know the Thirty-Nine Articles "hath not erred"? How do we know they hath not erred in the very act of telling us that "Popes and Councils hath erred"?
The Catholic Church is the work of Divine Providence, achieved through the prophecies of the prophets, through the Incarnation and the teaching of Christ, through the journeys of the Apostles, through the suffering, the crosses, the blood and the death of the martyrs, through the admirable lives of the saints. When, then, we see so much help on God's part, so much progress and so much fruit, shall we hesitate to bury ourselves in the bosom of that Church? For starting from the Apostolic Chair down through successions of bishops, even unto the open confession of all mankind, it has possessed the crown of teaching authority." -- St. Augustine of Hippo, Advantage of Believing, ca. AD 391

Because we have the comforter that shows us what is true.

Lets get to that, but first let is be established that inspiration is not to be confused with the novel and unScriptural premise of ensured perpetual magisterial infallibility as per Rome (unless you believe infallible decrees are inspired as Scripture is).
But since nobody is infallible, how do you know that's really true? How do you know the Apostle John really "explicitly wrote" it, anyway? How do you know there was an "Apostle John"? How do you "know" what "to know" means?
Thus your premise is that ensured perpetual magisterial infallibility is essential for the discernment of what is of God, correct?
But which premise invalidates the NT church, as it began with souls having rightly discerned both men and writings as being of God, and following an itinerant Preacher whom the historical magisterium/stewards of Scripture rejected, and whom the Messiah reproved them Scripture as being supreme, (Mk. 7:2-16) and established His Truth claims upon scriptural substantiation in word and in power, as did the early church as it began upon this basis. (Mt. 22:23-45; Lk. 24:27,44; Jn. 5:36,39; Acts 2:14-35; 4:33; 5:12; 15:6-21;17:2,11; 18:28; 28:23; Rm. 15:19; 2Cor. 12:12, etc.)
Thus under the Roman model your operate out of then you have nuked the church.
