Indeed “anybody can present nice neat words,” and indeed you should “always examine,” and thus we need to watch ourselves before we or you jump to conclusions.
For as you should know, a Messianic verse is not determined by whether all of the context is about Christ, and the very Psalm you disallow as having Messianic text is quoted from by the Holy Spirit as such more than once, even if some RCs think they knew better.
See right after the text at issue where it says,
“I am become a stranger unto my brethren, and an alien unto my mother’s children. For the zeal of thine house hath eaten me up; and the reproaches of them that reproached thee are fallen upon me. “ (Psalms 69:8-9)
And which is just what the Holy spirit in Jn. 2:17 states:
“And his disciples remembered that it was written, The zeal of thine house hath eaten me up. “ (John 2:17; cf. Rm. 15:3)
And there are more, for if Ps. 69:5 disallows v. 8 from speaking of Christ, as some reactionary Romans rule, then it would follow that Ps. 69:4 (They that hate me without a cause..) which is referenced in Jn. 15:25 cannot be either. And the same gospel that invokes Ps. 69:9 in applying it to Christ, also records that “His own received Him not,” “neither did His own brethren believe in Him.” (Jn. 1:11; 7:5)
In addition, while Catholics lack the extensive Scripture commentaries of evangelicals, the conservative Catholic Haydock commentary applies Ps. 69:8 to Christ as well, if not to His own siblings:
“Ver. 9. Mother. This might be true with respect to some apostate Jews. But it was more fully accomplished in Christ, who was betrayed by Judas, &c. (Calmet) -— His own received him not, John i. (Berthier)” haydock1859.tripod.com/id793.html
Also, contrary to your rule, Ps. 41:9 (“Yea, mine own familiar friend, in whom I trusted, which did eat of my bread, hath lifted up his heel against me”) which is confirmed (Jn. 13:18) to be prophetic of Christ, is nor disallowed as being such by v. 4 which states, “I said, LORD, be merciful unto me: heal my soul; for I have sinned against thee.”
But the reason Ps. 69:8 is disallowed as being prophetic of Christ is that “my mother’s children” is another example in which the most straight forward denotation would be the siblings of the subject.
THE Holy Spirit by the Apostles written down for the record but not to point out that there was brethren. Immediate brothers? Not jewish or christian brethren. That is amazing statement.
If you see my profile I had Biblical verses numbers put in awareness by the Holy Spirit which was 41:3 which I found to mean something in my own life. I had a health problem. This was after hours of praying. I found psalm 41:3 answered my problem. Does it mean everything is especially for myself to the exact content in every verse God sends my way?
The problem you present is exactly what does Apostolic succession mean. Does it mean I go by split hairs on verses from you or do I go by people who are have been there for two thousand years.
It is always Easy to criticize, but more difficult to be correct without being part of history. I will go by the historical accounts than other people thousands of years later.
