Paul VI was the one who specified that the form of the NREC is 42 words. He didn't say the form was the entire preface. Whereas the form of the Eastern Rites is universally agreed to be the entire preface. (...) But Paul VI said the NREC form is only 42 words and those 42 words don't specify the 2 criteria for a valid form. Spiritum Principalis (or equivalent) is indeed in the Eastern Rite forms but there is a lot more in them also which does meet Pope Pius's criteria.
You misrepresented what Paul VI said, as did Fr. Cekada. He did not limit the form to the 42 words. He explicitly stated that “the form consists of the words of the consecratory prayer,” and then added “of which" the 42 words belonged to the essence and therefore were required for validity. Here is what he wrote:
Paul VI: “Finally, in the ordination of a bishop, the matter is the laying of hands by the consecrating Bishops, or at least by the principal Consecrator, done in silence over the head of the Elect before the consecratory prayer; the form consists of the words of the consecratory prayer, of which the following belong to the essence, and are therefore required for validity. ‘So now pour out upon this chosen one that power which is from you, the governing Spirit whom you gave to your beloved Son, Jesus Christ, given by the Same to the holy Apostles, who founded the Church in each place, to be your sanctuary in the unceasing glory and praise of your name.’” (Source) As you can see, he merely specified which words of the form were essential for validity. He did not the limit the form to those words alone. The following is the entire form/consecratory prayer:. “Prayer of Consecration
“26. Next the principal consecrator, with his hands extended over the bishop-elect, sings the prayer of consecration or says it aloud:
“God the Father of our Lord Jesus Christ, Father of mercies and God of all consolation, you dwell in heaven, yet look with compassion on all that is humble. You know all things before they came to be; by your gracious word you have established the plan of your Church. From the beginning you chose the descendants of Abraham to be your holy nation. You established rulers and priests, and did not leave your sanctuary without ministers to serve you. From the creation of the world you have been pleased to be glorified by those whom you have chosen.
[The following part of the prayer is recited by all the consecrating bishops, with hands joined:]
“So now pour out upon this chosen one the power that is from you, the governing Spirit whom you gave to your beloved Son, Jesus Christ, the Spirit given by him to his holy apostles, who founded the Church in every place to be your temple for the unceasing glory and praise of your name.
[Then the principal consecrator continues alone.]
“Father, you know all hearts. You have chosen your servant for the office of bishop. May he be a shepherd to your holy flock, and a high priest blameless in your sight, ministering to you night and day; may he always gain the blessing of your favor and offer the gifts of your holy Church. Through the Spirit who gives the grace of high priesthood grant him the power to forgive sins as you have commanded, to assign ministries as you have decreed, and to loose every bond by the authority which you gave to your apostles. May he be pleasing to you by his gentleness and purity of heart, presenting a fragrant offering to you, through Jesus Christ, your Son, through whom glory and power and honor are yours with the Holy Spirit in your holy Church, now and for ever. R. Amen.”
“27. After the prayer of consecration, the deacons remove the Book of the Gospels which they have been holding above the head of the new bishop. One of them hold the book until it is given to the bishop. The principal consecrator and the consecrating bishops, wearing their miters, sit.” (source) There is no doubt whatsoever that this is a valid form for episcopal consecration. Not only is it virtually identical to that which St. Hippolytus said was used by the Apostles themselves, but it clearly and unambiguously satisfies the requirements specified by Pius XII.
