Let me turn it around. You, and the Catholic Church, deny the truth of Sola Scriptura and Sola Fide. Does that mean that you feel it is impossible that God could have chosen Scripture Alone and Faith Alone?
The doctrine of Sola Scriptura and Faith Alone was developed by Martin Luther in 1517-30. These doctrines are unheard of and are completely foreign and alien to the orthodoxy of Christianity. Even the Eastern Orthodox reject these two pillars of Protestantism.,
The Catholic Church believes that the Word of God is Sacred Scripture and Sacred Tradition, and the Magisterium itself has the Sole authority to interpret them correctly. Otherwise, if you read Scripture you can interpret in many ways, and even distort the context of the Gospel.
Sola Scriptura and Faith Alone is not from God. It’s from a man, Martin Luther and other Protestant Reformers. Paul made this clear when he said, “Jesus Christ is the same yesterday, today, and forever. Therefore, do not teach any strange doctrine.”
We see so many essential beliefs within Protestantism itself. Some believe the necessary of infant baptism, or that baptism saves. It seem to me that the Holy Spirit is giving different message to one Protestant Minister to the Next. So which one of the minister is telling the truth? The Holy Spirit is not the Holy Spirit of confusion.
Failing to believe something is not the same as saying it could not be done. Could the Immaculate Conception have occured. Most certainly it could have. Did it? I don’t know, it is possible that it did take place but I am not convinced that it did, not that it couldn’t happen.
Immaculate Conception is professed by the Church basing itself on Sacred Tradition and Sacred Scripture. Like the Trinity, this was defined to get a better understand of the nature of Jesus.
You have made the statement that some Protestants are saying that that some things are impossible with God. I ask you to provide even one link confirming any such belief by any Protestant. And I mean a real Protestant, not just a non-Catholic. ie groups like Jehovah Witnesses are not Protestant although I doubt that they question the omnipotence of God.
Let us take the issue and belief that Jesus Christ is truly present in the Blessed Sacrament. His Body, Blood, Soul, and Divinity is present. You know of course Catholics and Orthodox and some Protestants affirm this belief. Yet, there are those Protestants who believe that the Holy Eucharist is only symbolic.
The Church declare that during the Consecration the Body and Blood becomes Jesus. The Eastern Christians haven’t defined their when this actually take place but affirms the Real Presence of Jesus Christ.
Those Protestants who say that the Eucharist is not Jesus and it is symbolic have gone at length by declaring Catholics as idolators for worshipping the “Bread of Life.” Why do they deny the Real Presence, when Scripture itself makes it clear that Jesus’ flesh is real food and his Blood is real drink? Can’t God make bread as his body and the wine as his blood? I believe God who created all things can make this possible because with God all things are possible.
