Dear one, precious sister, when I first read your post I thought, she's right and I asked myself why, what's the use?
First may I respond to what you have inferred as human logic, it's not human logic, it's wisdom taught to God's children by the Holy Spirit 1 Jn 2:27, it's understanding Old Testament prophesy about our Lord, over 300 prophesy's about the birth, life, death and resurrection of Jesus, ...and he fulfilled every one of them, I humbly ask in brotherly love, ...how many of the 300 do you know and understand, this isn't a put down, it's meant as an encouragement to cause you search the Scriptures and grow in the grace and the knowledge of our Lord Jesus Christ, to study to show yourself approved so that you will not be deceived and will be able to teach others.
As to the why?
We are indebted to the Jewish scribes for their perseverance and fidelity in preserving the Word of God of the Old Testament pure and undefiled for us, you and me personally, we hold in our hands the actual Word of God as spoken and inspired by the Holy Spirit to the Old Testament writers.
Let me explain, the Jews used their alphabet to count with, i.e., a=1, b=2, c=3, etc. (using English as an example), when they would copy a scroll they added up the sum of the letters and if the sum was not the same as the original they didn't look for the error, they burned the scroll, ...it's recorded a scribe was so familiar with his work he could pass a needle through the scroll and tell us what letter had been pierced by the needle, ...a requirement for requiting new scribes.
We know from the discovery of the Qumran Scrolls in the '40s and a practically complete scroll of the Book of Isaiah, when compared to the original texts our Bibles have been translated from, they were identical.
With that in mind, we, you and me, this generation, have been passed the torch to continue to keep the Word of God pure and unadulterated for the next generation. The enemy of our souls is also the enemy of the Word of God and he has been trying to change, add to or take from what God has said since his encounter with the first human in the Garden, here is the admonition and warning Paul has left us,
But I fear, lest by any means, as the serpent beguiled Eve through his subtilty, so your minds should be corrupted from the simplicity that is in Christ. For if he that cometh preacheth another Jesus, whom we have not preached, or if ye receive another spirit, which ye have not received, or another gospel, which ye have not accepted, ye might well bear with him. 2Co 11:3, 4
For such are false apostles, deceitful workers, transforming themselves into the apostles of Christ. And no marvel; for Satan himself is transformed into an angel of light. Therefore it is no great thing if his ministers also be transformed as the ministers of righteousness; whose end shall be according to their works. 2Co 11:13-15
I'll let Jesus himself and the writers of the New Testament tell you why,
Beware of false prophets, which come to you in sheep's clothing, but inwardly they are ravening wolves. Mat 7:15
And as he sat upon the mount of Olives, the disciples came unto him privately, saying, Tell us, when shall these things be? and what shall be the sign of thy coming, and of the end of the world? And Jesus answered and said unto them, Take heed that no man deceive you. Mat 24:3, 4
And from Miletus he (Paul) sent to Ephesus, and called the elders of the church. Act 20:17
For I have not shunned to declare unto you all the counsel of God. Take heed therefore unto yourselves, and to all the flock, over the which the Holy Ghost hath made you overseers, to feed the church of God, which he hath purchased with his own blood. For I know this, that after my departing shall grievous wolves enter in among you, not sparing the flock. Also of your own selves shall men arise, speaking perverse things, to draw away disciples after them.Therefore watch, and remember, that by the space of three years I ceased not to warn every one night and day with tears. Act 20:27-31
Now I beseech you, brethren, mark them which cause divisions and offences contrary to the doctrine which ye have learned; and avoid them. Rom 16:17
For first of all, when ye come together in the church, I hear that there be divisions among you; and I partly believe it. For there must be also heresies among you, that they which are approved may be made manifest among you. 1Co 11:18, 19
For we are not as many, which corrupt the word of God: but as of sincerity, but as of God, in the sight of God speak we in Christ. 2Co 2:17
That we henceforth be no more children, tossed to and fro, and carried about with every wind of doctrine, by the sleight of men, and cunning craftiness, whereby they lie in wait to deceive; Eph 4:14
Beware lest any man spoil you through philosophy and vain deceit, after the tradition of men, after the rudiments of the world, and not after Christ. Col 2:8
Now the Spirit speaketh expressly, that in the latter times some shall depart from the faith, giving heed to seducing spirits, and doctrines of devils; Speaking lies in hypocrisy; having their conscience seared with a hot iron; 1Ti 4:1, 2
But refuse profane and old wives' fables, and exercise thyself rather unto godliness. 1Ti 4:7
Dear one I congratulate you if you have made it this far, do you see what Paul has said to us, a Friday crucifixion is profane and an old wives' fable perpetrated and perpetuated by the RCC and is refuted by both the Old and New Testaments.
I serve my Lord and His Church to hear Him say, Well done, good and faithful servant, ...and that, my beloved sister, is my heartfelt desire for you to receive the same approbation.
Blessing in His Love
