Catholics call it a finished work as that which provides grace but then according to the law of their fathers show it to be a partial payment of a unknow amount of grace. Saying our work of suffering in the end of the matter a a place they call purgatory does the actual finishing.
Therefore we must find out what they mean when they use the word "finsished" it has another meaning like they do with many of the words of scripture
So then we have Christ's work as incomplete and a hope of completing it for another unknown amount of time or severity of suffering in the end .
It's how a person looks at the work. Protestants have a different view of (it is finished) Christ supplied the fulness of His grace .There is no grace coming from the creatures. Like our sister in the Lord Mary is the mother of mercy y as if she was crucified for the sins of the world.
Therefore they simply do despite to the grace of God
The Catholics because there foundation is built seeking after dead people who are no longer here under the Sun, they have developed a system of seeking (necromancy) the approval of workers with familiar spirits. They create their own private faith base that they are required to call Patron saint.
Patron saints (3500 and rising) makes up that legion The same amount of idol images (teraphims) are available to purchase . In that way when the legion comes up they have a face to connect with the unseen spirit.
The apostate jews followed the same order.. different workers with famialr spirits. Rachel who practiced a form of Catholicism hid them from her father.He most likely had new ones made up.
Genesis 31:34 Now Rachel had taken the images, and put them in the camel's furniture, and sat upon them. And Laban searched all the tent, but found them not.
I follow neither Catholic nor Protestant doctrine/dogmas I read the Bible, pray for the spirit to help me figure out what it all means and discuss it with others. Among protestants for example th differences between Assemblies of God vs Baptists vs Lutherans vs Quakers etc. Who's to decide? Or should we question them all against the word and trust that will reward our efforts more than if we say yea and amen to whatever we are taught? I surely know it all, God has infinite wisdom, not me. I do know Jesus is the Christ, Son of the living God, Born of A Virgin without the sin of mankind upon him. He was persecuted, tormented, tempted by the Devil himself he allowed himself to be executed for our sake in our place. He was placed in a tomb, dead on Friday, on the eve of passover. Sunday he walked out. He went to the disciples who ran out and denied him. He even proved himself to them. Later he rose to heaven while still alive and he's coming back for us I bet my life and eternal soul on it. That's all I know. Most everything else is either I think or I hope may the Lord please forgive me and/or correct me where I am wrong.
