Paul's interpretation of his experience is what people today might call his truth

 

Have I not seen Jesus Christ our Lord?

-- I Corinthians 9:1

And last of all he was seen of me also, as of one born out of due time.

-- I Corinthians 15:8  

The salient points in the three accounts of Paul's conversion in Acts are that he could not see who was talking to him because he was blinded by the light, and that he did not recognize who it was that was speaking to him:

And as he journeyed, he came near Damascus: and suddenly there shined round about him a light from heaven: ... Who art thou, Lord? ... And Saul arose from the earth; and when his eyes were opened, he saw no man: but they led him by the hand, and brought him into Damascus. And he was three days without sight, and neither did eat nor drink. 

-- Acts 9:3, 5, 8f.

And it came to pass, that, as I made my journey, and was come nigh unto Damascus about noon, suddenly there shone from heaven a great light round about me. ... Who art thou, Lord? ... And when I could not see for the glory of that light, being led by the hand of them that were with me, I came into Damascus.

-- Acts 22:6, 8, 11

At midday, O king, I saw in the way a light from heaven, above the brightness of the sun, shining round about me and them which journeyed with me. ... Who art thou, Lord? 

-- Acts 26:13, 15.

Nevertheless he calls it "seeing" the Lord. 

Meanwhile the witnesses in Acts 9 heard only a voice, and saw no one.

In Acts 22 the witnesses saw only the light, and heard nothing.

In Acts 26 Luke has Paul say that he and the witnesses were knocked to the ground after being enveloped by the light.

Most notably there, Luke has Paul summarize the whole experience explicitly as a heavenly vision, which is the experience through which Paul says elsewhere that he received his gospel (II Corinthians 12:1, 7; Galatians 1:12, 16; 2:2; Romans 16:25; Ephesians 3:3, 5), whereupon the governor Festus pronounced Paul a madman.

No one "saw" the Lord in the Acts accounts, but in the final analysis Paul's claims to have seen the Lord are unfalsifiable because they are heavenly and beyond our ken. They are as a result self-insulating and self-authenticating.

LOL, The Lutheran World Federation just canceled The Nicene Creed in The West

Rev. Anne Burghardt, General Secretary of the Lutheran World Federation

 

The Lutheran World Federation just resolved the problem of the insertion of the filioque with a reactionary surrender to the Orthodox, jettisoning reason for emotion.

"Let's just recite The Nicene Creed without 'and the Son' and then we can be friends". 

. . . we suggest that the translation of the Greek original (without the Filioque) be used in the hope that this will contribute to the healing of age-old divisions . . ..

Here.

Is there a better example in the long history of Christian theology of the failure of the church to be guided into all the truth?

The Protestant schism is only 507 years old, the East-West now 970.

The filioque was a reasonable development within Trinitarianism, stubbornly resisted by the church in the East because it wasn't explicitly Nicene (325). Its first known promulgation at the Third Council of Toledo in 589 in a context of Arianism, the primarily Eastern heresy from the early fourth century, spread in the West but rankled the East, so much so it became a red line by 1054.

They got tired of their reputation for mistakes, I guess.

The first Protestant Reformers insisted generally on the text of Scripture to guide into all the truth, in keeping with the thinking of ancient fathers of the church such as Athanasius and Cyril of Alexandria, and Epiphanius of Salamis, who specifically on the subject of the procession of the Holy Spirit from both the Father "and the Son" thought it was the plain teaching of the New Testament.

The Reformers thought that the New Testament Scriptures were the result of that process described by Jesus in the Gospel of John, that the Spirit would guide into all the truth. To them the filioque was obvious.

Howbeit when he, the Spirit of truth, is come, he will guide you into all truth: for he shall not speak of himself; but whatsoever he shall hear, that shall he speak: and he will shew you things to come. He shall glorify me: for he shall receive of mine, and shall shew it unto you. All things that the Father hath are mine: therefore said I, that he shall take of mine, and shall shew it unto you.

-- John 16:13ff.

To contemporary Lutherans? Not so much.

Intellectually, if we may use that term elastically, the liberal Lutherans now have more in common with the enthusiasts, the Schwärmer, the 16th century's charismatics and radicals, than they do with the Protestant Reformation.

To them the Spirit is still revealing truths to all and sundry: His truth, her truth, my truth, your truth, hir truth, their truth, but the more important thing is the feeling of unity. Besides, most Christians today have no clue about an obscure topic like the filioque. It's a speedbump, not a roadblock.

The way for this in liberal Lutheranism was prepared for by their enthusiastic embrace of modern critical scholarship of the Bible, with the result that everything has been up for grabs: The theory of evolution, women's ordination, homosexuality, et cetera, et cetera, et cetera. Hey, why not the filioque? "Just take it . . . to the limit . . . one more time."

The origins of that, however, ironically enough, are in the Enlightenment rediscovery of . . . reason. What goes around, comes around, you might say, as the phonograph needle scratches across the vinyl.

Ultimately speaking, neither the well of human reason nor the well of human feeling produces rivers of living water.

I have seen all the works that are done under the sun; and, behold, all is vanity and vexation of spirit. 

-- Ecclesiastes 1:14

The Fourth Gospel is conveniently self-authenticating and self-insulating about the reliability of the church's recollection of the teaching of Jesus

 But the Comforter, which is the Holy Ghost, whom the Father will send in my name, he shall teach you all things, and bring all things to your remembrance, whatsoever I have said unto you.

 

-- John 14:26

 

I have yet many things to say unto you, but ye cannot bear them now.  Howbeit when he, the Spirit of truth, is come, he will guide you into all truth: for he shall not speak of himself; but whatsoever he shall hear, that shall he speak: and he will shew you things to come. 

 

-- John 16:12f. 

 

This reflects the essential "my truth" enthusiasm at the heart of early Christianity without which there would be no St. Paul with his Christ mysticism.

 

This is the true origin of individualism and subjectivism in the West. It is ultimately self-defeating because it leads logically to relativism.

Love thy neighbor this, and love thy neighbor that, but they always seem to leave this part out

 

. . . You shall surely rebuke your neighbor, and not bear sin because of him.

-- Leviticus 19:17

Lying by omission is our way of life here in America, in service of our "live and let live" ideology, perhaps made most famous in the old "Don't ask, don't tell" policy of Bill Clinton about gays in the military.

Truth no longer exists. There is only "my truth".

Libertarianism = injustice.
