Of course they are Biblical because they are instituted by Christ to give grace.
Because RCC believes in apostolic succession and Godly members of RCC clergy are successors of the apostles.
The apostles were given by Jesus the power to forgive sin as mentioned in John Chapter 20.
then it was passed to the successors.
I really can't fathom how some newly established sects telling they are Born Again but has no existence since 1st century and its pastors are not even successors of the Apostles.
perhaps most of these "Born again" groups are indeed business using God's words to get a lot of money from its members by their greedy pastors and even police will join these groups and these groups will never be persecuted by the law.
some politicians might even ask support and some votes from these so called "Born again" groups.
No sacraments, that can be purchased with $$$$$ as self-glorifying or edifying works a person does to give the illusion as an outward sign to confirm the filling of the Holy Spirit.
The RCC who preach another gospel other than all things written in the law and the prophets (sola scriptural) added a new meaning to the word "apostle" and in doing so violated the warning in Deuteronomy 4:3
2 Ye shall not add unto the word which I command you, neither shall ye diminish ought from it, that ye may keep the commandments of the Lord your God which I command you.Deuteronomy4;3
It is a different warning than the one in the chapter or book of Revelation in so much that it is in respect to the whole bible not to add or subtract while the Deuteronomy warning is in respect to one word. The Holy Spirit required both warning to be obeyed in order to protect the integrity of His living abiding word.
The English word "sent one" can be used to replace the Greek form of sent one(apostle)
The RCC have simply confused the meaning in a hope to take way the authority of God's word (sola scriptura) giving it to men .
All of those sent out into the world with the good news would be consider sent ones (apostles)
Mark 16:15And he said unto them, Go ye into all the world, and preach the gospel to every creature.
The 12 a remnant of all the apostles listed by name in the new testament (25)are set aside for a certain purpose to be used as metaphors in various parable for a particular purpose .( 12 represent the authority of God)
Again, those who add meaning to a single word violate the law not to. Can changing one meaning can change the authors original intent
I would think in the true sense of the word ( sent one apostle) Abel in whom God sent was the first apostle. His brother did not desire to hear the good news so He killed him
If thou doest well, shalt thou not be accepted? and if thou doest not well, sin lieth at the door. And unto thee shall be his desire, and thou shalt rule over him.And Cain talked with Abel his brother: and it came to pass, when they were in the field, that Cain rose up against Abel his brother, and slew him.Geneisis 4
