Wikipedia says that the Didache was anonymous, and "may have been compiled in its present form as late as 150, although a date closer to the end of the first century seems more probable to many", so it was not written by the Apostles. "The work was considered by some Church Fathers to be a part of the New Testament, while being rejected by others as spurious or non-canonical. In the end, it was not accepted into the New Testament canon".
This is another example of men adding to the Word of God, and it should be ignored! There is certainly no Biblical evidence to suggest that anyone was told or required to fast for one or two days before being baptised! The opposite was the case (Acts 8:36-38, WEB):
36) As they went on the way, they came to some water, and the eunuch said, “Behold, here is water. What is keeping me from being baptized?”
38) He commanded the chariot to stand still, and they both went down into the water, both Philip and the eunuch, and he baptized him.
Note that verse 37 has been removed from this passage in many modern translations, because it was a later addition that is not in the older manuscripts - another example of an alteration! Verse 37 (KJV) says:
And Philip said, If thou believest with all thine heart, thou mayest. And he answered and said, I believe that Jesus Christ is the Son of God.
The Cambridge Bible notes says:
The whole of this verse is omitted in the oldest MSS. It probably found its way into the text of those MSS. where it does exist from the margin. Such a margin would be formulated by those who, when the Church had become more extended, and formal professions of faith were the rule before baptism, felt that there was a want of completeness in the narrative unless some such confession were supposed to have been made. Thus the margin became a kind of exposition, and in the end found acceptance in the text.
Authority of the Apostles!
What authority does Christ have?
What power does Christ have?
What mission / ministry does Christ have?
Peter, the apostles and their successors have the same authority, power, and mission! Jn 20:21 as my father sent me, even so send I you!
The apostles are Christ’s successors!
They have authority to send others as well, apostle means one who is sent!
Therefore the apostles have authority to send more apostles or successors!
Apostolic succession!
The nations still need to be taught, disciples still need to be baptized and the church the new covenant kingdom of christ still needs to be governed!
Hebrews 3:1
Wherefore, holy brethren, partakers of the heavenly calling, consider the Apostle and High Priest of our profession, Christ Jesus;
Christ is an apostle, and has authority to send other apostles, the apostles also have this authority, so the apostles continue down thru the centuries as Christ promised! Matt 28:19-20
Keys of authority! And power to bind and loose! Matt 16:18 and Matt 18:18 matt 28:19
Moral authority:
(Teaching)
Necessity of being taught by Christ:
Two edge sword: defining truth and condemning errors, and Interpreting scripture.
Jurisdictional authority:
(Governing / administering)
Necessity of Peter and the apostles and their successors to govern the holy church.
Spiritual authority:
(Life of Grace)
Sanctifying thru the mass and Sacraments
Jesus Christ continues HIS ministry in His new covenant church thru Peter, the apostles, and their successors with the same mission, power, and authority!

Only the church has authority from Christ to define the truth and teach!
