No one is born knowing the truth. As such, a person needs to seek out the truth. Truth is as such disseminated by teachers.
The matter of discerning which teachers are teachers of the truth and which ones are teachers of falsehood is a difficult one.
One might turn to the writings of teachers already dead, but if so one must understand them without the possibility of further explanation. One who is by nature ignorant of the truth may not be able to of his own power.
Neither the position of the Catholics nor that of the followers of Luther are without the potential for error.
Catholics believe Jesus taught the apostles, who taught their own disciples, and thus carried down a living tradition of the truth through the established heirarchy. History shows, however, that to some extent the Papacy has had periods where divine providence has not always resulted in the best Popes. Yet the Church recovers from such failings and moves on. It is a pilgrim church.
Protestants believe Jesus taught the apostles, and the apostles (and St. Paul) wrote the books of the New Testament. They believe that by studying this document, with the aid of the Holy Spirit, all truth may be laid bare. The flaw with such an idea is were the Holy Spirit already had, there would be no need for the scriptures at all as surely the Spirit does not need them.
Those who know the truth need no other teacher than the Holy Spirit. But we must must be on our guard, not only against false teachers, but abandoning a true teacher before we have learned everything, making ourselves into spiritual abortions. If Jesus felt man needed no teachers he would not have taught himself, and instructed his followers to teach others.
While you may doubt the veracity of the Catholic Church, and surely in its imperfect body there are false teachers, you can not doubt the wisdom that those who are imperfect should be under the instruction of a superior.
IIRC there is evidence for Purgatory in Maccabees.
The belief in Purgatory goes hand in hand with sanctifying grace, which a soul can be deprived of through mortal sin according to the Catholic teaching.
Since Protestants following Luther do not believe one needs to leave a life of mortal sin in order to have sanctifying grace for salvation, they have no need in their theology for a safe haven for those with only venial sins.
Yet ritual, an an outward sign, can demonstrate to others what the truth is that is held by its followers. Why Protestants go to church, or even have churches is beyond me if they so disagree with this idea.
Ah, but Paul taught this, not Christ, so we shouldn’t listen to him!
But then you are merely your own authority, prone to your own weak understanding. To this day I do not understand why so many Protestants have Bible school. And I can not believe that they all come to the same understanding, quite apart from their indoctrination, merely by the Holy Spirit – which often happens to be the exact same understanding as Luther had though his ideas never occured to anyone in Christiandom for a thousand years. And then they burst forth from years of Bible school and rant that no one should have any teachers!
Fortunately, Jesus presented a solution to this whole dilemma. Keep his commandments, which are clear imperatives, and the Spirit of Truth will be sent to you. You shall know the truth, and the truth shall set you free.
(BTW, UnuMondo – perpetual adoration is a good thing. We might wonder on the other hand why Protestant churches keep their doors locked most hours of the day, which violates the whole spirit of Jesus’s teachings. The perpetual adoration an attempt to keep the doors open and I would hope one day no Catholic Church ever locks its doors.)
