Actually, it's a Biblical understanding of His authority. Roman Catholicism undermines His authority with its insistence on the worship of Mary and equating her as co-redemptrix, advocatrix, etc.
But here is what they almost universally miss: Just about every time the New Testament reveals the radical nature of Christ’s authority, you will find in close proximity Christ then giving a similar authority to the Church.
Matt. 28:18-20:
… All authority in heaven and on earth has been given to me. Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, teaching them to observe all that I have commanded you; and lo, I am with you always, to the close of the age
(the implication is go with my authority).
Whoa....where do you get this last part from? Your opinion? Or is this official Roman Catholic dogma? We've been told that you, as a Roman Catholic, cannot read and understand Scripture on your own.
This is not the church. There were far more believers than just the eleven.
But you ignore these words of Jesus: “Jesus said to them, “Amen, amen, I say to you, unless you eat the flesh of the Son of Man and drink his blood, you do not have life within you. 54Whoever eats* my flesh and drinks my blood has eternal life, and I will raise him on the last day.”
As all Roman Catholics ignore these words: 35Jesus said to them, “I am the bread of life; he who comes to Me will not hunger, and he who believes in Me will never thirst. John 6:35 NASB
I'm willing to bet you had breakfast, lunch and will most likely have dinner. And I'm willing to bet you were thirsty today.
If the Roman Catholic wants to take John 6:53 as literal then they have to take 6:35 as literal as well.
But you don't because you've eaten food today.
Roman Catholicism cannot even be consistent in its rendering of 23 verses of Scripture!
