Then Joseph being raised from sleep did as the angel of the Lord had bidden him, and took unto him his wife:
And knew her not till she had brought forth her firstborn son: and he called his name Jesus."
He didn't have sex with her
until after she gave birth to her firstborn son. Then he did. The word till shows a difference between before and after. Otherwise the word until wouldn't be there.
1 Timothy 4:13
"Until I come, attend to the public reading of scripture, to preaching, to teaching."
Does this mean that Timothy should stop reading scripture, preaching, and teaching?
Timothy was to attend to the public reading of scripture and preaching until Paul comes to take over the meetiings. So when Paul is not there, Timothy was to do it; and when Paul was there Paul would do the teaching.
1 Corinthians 15:25
"For He (Christ) must reign until he has put all his enemies under his feet."
Does this mean that Christ's reign will end?
Yes Christ's reign over the nations will end. Christ will reign over the nations for 1000 years. And at the end of the thousand years the wicked will be cast into the lake of fire. We will have a new heaven and a new earth and God will not reign over us, but He will be our God and we will be His sons and daughters.
And they lived and reigned with Christ for a thousand years. 5 But the rest of the dead did not live again until the thousand years were finished. This
is the first resurrection. 6 Blessed and holy
is he who has part in the first resurrection. Over such the second death has no power, but they shall be priests of God and of Christ, and shall reign with Him a thousand years.
7 Now when the thousand years have expired, Satan will be released from his prison 8 and will go out to deceive the nations which are in the four corners of the earth, Gog and Magog, to gather them together to battle, whose number
is as the sand of the sea. 9 They went up on the breadth of the earth and surrounded the camp of the saints and the beloved city. And fire came down from God out of heaven and devoured them. 10 The devil, who deceived them, was cast into the lake of fire and brimstone where the beast and the false prophet
are. And they will be tormented day and night forever and ever.
The Great White Throne Judgment
11 Then I saw a great white throne and Him who sat on it, from whose face the earth and the heaven fled away. And there was found no place for them. 12 And I saw the dead, small and great, standing before God, and books were opened. And another book was opened, which is
the Book of Life. And the dead were judged according to their works, by the things which were written in the books. 13 The sea gave up the dead who were in it, and Death and Hades delivered up the dead who were in them. And they were judged, each one according to his works. 14 Then Death and Hades were cast into the lake of fire. This is the second death. 15 And anyone not found written in the Book of Life was cast into the lake of fire.
21 Now I saw a new heaven and a new earth, for the first heaven and the first earth had passed away. Also there was no more sea. 2 Then I, John, saw the holy city, New Jerusalem, coming down out of heaven from God, prepared as a bride adorned for her husband. 3 And I heard a loud voice from heaven saying, “Behold, the tabernacle of God
is with men, and He will dwell with them, and they shall be His people. God Himself will be with them
and be their God. 4 And God will wipe away every tear from their eyes; there shall be no more death, nor sorrow, nor crying. There shall be no more pain, for the former things have passed away.”
5 Then He who sat on the throne said, “Behold, I make all things new.” And He said to me, “Write, for these words are true and faithful.”
6 And He said to me, “It is done! I am the Alpha and the Omega, the Beginning and the End. I will give of the fountain of the water of life freely to him who thirsts. 7
He who overcomes shall inherit all things, and I will be his God and he shall be My son.
And yes, Jesus had brothers, but in Orthodoxy, we recognize the fact that Joseph was a widow before he got married to Mary, and they are step brothers of Jesus. James, the Brother of Jesus, would be the main ruler of the Church of Jerusalem while the other Apostles preached the Gospel around the known world.
This is not in Scripture, but a fairytale made into a "holy tradition."
There is always a before and after when you have a "till" or "until." Mary was a virgin until Christ's birth, but after that she was Joseph's wife, and he didn't touch her until after the baby was born, but then he gave her sons and daughters.
The virgin birth isn't tainted just because she was Joseph's normal wife after Christ was born. It is only when people want to venerate Mary above her station of just becoming one of Christ's disciples that is adding to scripture and forbidden. But Orthodoxy seems to think they have the power to change Scripture to fit fairytales.
