Heb 8 says this -
Now the main point in what has been said is this: we have such a high priest, who has taken His seat at the right hand of the throne of the Majesty in the heavens, 2 a minister in the sanctuary and in the true tabernacle, which the Lord set up, not man. 3 For every high priest is appointed to offer both gifts and sacrifices; so it is necessary that this high priest also have something to offer. 4 Now if He were on earth, He would not be a priest at all, since there are those who offer the gifts according to the Law; 5 who serve a copy and shadow of the heavenly things, just as Moses was warned by God when he was about to erect the tabernacle; for, “See,” He says, “that you make all things by the pattern which was shown to you on the mountain..
So then
1. A real sanctuary in heaven
2. Made by God
3. The PATTERN from which Moses took to make a miniature basic model for the sanctuary in the wilderness.
4. Christ ministers as High Priest in that sanctuary in heaven at the right hand of the Father.
5. If He were on Earth He would not be a priest at all.
None of those details in heaven - seen/reported by any other NT writer. We know it from scripture.
yep
nor of 31 AD or 34 AD or whenever you might want to say the date was for Christ's ascension to heaven to take up that role as High Priest in the heavenly sanctuary -- yet there it is in Heb 8.
Heb 9:
8 The Holy Spirit is signifying this, that the way into the holy place has not yet been disclosed while the outer tabernacle is still standing, 9 which is a symbol for the present time. Accordingly both gifts and sacrifices are offered which cannot make the worshiper perfect in conscience,
11 But when Christ appeared as a high priest of the good things having come, He entered through the greater and more perfect tabernacle, not made by hands, that is, not of this creation; 12 and not through the blood of goats and calves, but through His own blood, He entered the holy place once for all time, having obtained eternal redemption. ...
15 For this reason He is the mediator of a new covenant, ...
18 Therefore even the first covenant was not inaugurated without blood. 19 For when every commandment had been spoken by Moses to all the people according to the Law, he took the blood of the calves and the goats, with water and scarlet wool and hyssop, and sprinkled both the book itself and all the people, 20 saying, “This is the blood of the covenant which God commanded you.” 21 And in the same way he sprinkled both the tabernacle and all the vessels of the ministry with the blood. 22 And almost all things are cleansed with blood, according to the Law, and without the shedding of blood there is no forgiveness.
23 Therefore it was necessary for the copies of the things in the heavens to be cleansed with these things, but the heavenly things themselves with better sacrifices than these. 24 For Christ did not enter a holy place made by hands, a mere copy of the true one, but into heaven itself, now to appear in the presence of God for us;
Heavenly things , in the heavenly sanctuary - cleansed with "Better sacrifices" - ie the blood of Christ.
The heavenly holy place rather than an earthly one.
We just read it. Just when you say "no cleansing" mentioned - we see in chapter 9 "the cleansing" in heaven.
