Note to self. When writing about what is possible with God, always quote Luke 1:37. Surely no one can disagree with what the angel Gabriel said to Mary.
Surely a thinking person can disagree with Rome's teaching that Mary AGREED to what was told WAS going to happen to her.
Actually, there are things that are not possible.
He cannot sin, for example.
Once you strip a verse from its context and try to make it a universal saying, you run into problems.
Again, we are back to “study to show yourself approved, a workman who rightly handles the Word of Truth,” and “... Love the Lord your God with all your ... mind.”
That is moving the goal posts. For that God can do miracles is not the issue that what must be proved by you, but that He is doing the miracle your make Him out to be doing. Based upon your "nothing is impossible with God = whatever Rome says God does" hermeneutic, you could teach that Mary split the Red Sea, feed 5,000 souls with bread crumbs, and is ruling a distant planet. But sound theology, and binding beliefs cannot be based upon what God could do, but upon what His wholly inspired revelation teaches. Upon which core Christians beliefs have clear and substantial testimony in Scripture, even with theological exposition for basic salvific doctrine.
Thus the Holy Spirit would not fail to describe the Catholic priesthood in the life of the NT church offering the LS as a sacrifice for sin to be consumed in order to obtain spiritual life, as the central sacrament of the church. But not only is this utterly absent, but the only priesthood is that of all believers, who are all called to sacrifice, and spiritual life is obtained and nourished via preaching of the word, which is spirit and life, and which is the primary active function of NT pastors.
Of course, such is only part of the absence of Catholicism in Scripture, the substantially "invisible church."
