One thing Protestant do not understand is that the saints form a communion with us. They are the "we" in Our Father. When we pray, we pray in their company.
Mobving on to your subsequent 237, 239.
you twist and add to His words about the Supper being an enduring testimony and remembrance of His atoning death for us, something that He and He alone has completed for the salvation of mankind, and in so doing transmogrify what is purely sacramental, purely gracious forgiveness, into something altogether different and sacrificial, something that, by its very doing, you contend, adds to an imagined treasury of merits.
What is it that I added and "trannsmogrified"? The "treasure of merits" is a term that is applied to all good works done by Christians for the benefit of salvation of others (Merit). It is not really a part of the Mass per se, although, of course, like I said earlier, it is with the Communion of saints that the Mass is celebrated:
9 ...I saw a great multitude, which no man could number, of all nations, and tribes, and peoples, and tongues, standing before the throne, and in sight of the Lamb, clothed with white robes, and palms in their hands: 10 And they cried with a loud voice, saying: Salvation to our God, who sitteth upon the throne, and to the Lamb.11 And all the angels stood round about the throne, and the ancients, and the four living creatures; and they fell down before the throne upon their faces, and adored God, 12 Saying: Amen. Benediction, and glory, and wisdom, and thanksgiving, honour, and power, and strength to our God for ever and ever. Amen. 13 And one of the ancients answered, and said to me: These that are clothed in white robes, who are they? and whence came they? 14 And I said to him: My Lord, thou knowest. And he said to me: These are they who are come out of great tribulation, and have washed their robes, and have made them white in the blood of the Lamb. 15 Therefore they are before the throne of God, and they serve him day and night in his temple: and he, that sitteth on the throne, shall dwell over them.
16 They shall no more hunger nor thirst, neither shall the sun fall on them, nor any heat. 17 For the Lamb, which is in the midst of the throne, shall rule them, and shall lead them to the fountains of the waters of life, and God shall wipe away all tears from their eyes.
(Apoc. 7)
Your idea of “rich” is to add man-chosen elements that detract from Christ’s completed vicarious atonement
It is true that the Chruch is authorized by Christ to choose the precise form of worship as it is generally authorized to "bind and loose" on Earth (Matthew 16:19, 18:18). The essential parts of the Mass are, however, wholly scriptural, as my post 233 explains. If you have a particular question, I will be happy to answer.
(2 Corinthians 8:9)
... urges the same spiritual abundance ("as in all things you abound in faith, and word, and knowledge, and all carefulness; moreover also in your charity towards us, so in this grace also you may abound") in verse 7 that exists in the Catholic worship/ The "poverty of Christ" should not be confused with Protestant philistine artlessness, even less with self-inflicted separation from the Communion of saints in heaven praying for your conversion.
I speak Scripture. You speak Roman dogma.
It would appear to me that ne’er the twain shall meet.
