I agree that the above information is not without error. Joseph and Mary did have a marital relationship. It is safe to say this because of the references to his brothers in Mt 12: 46-50 and Acts 1:14. Also in Mt 1:20-25 an angel of the Lord instructs Joseph to wed Mary now but he asks that he not have relations with her until the birth of Jesus.
Matthew 1:25 – “Until”
Matthew 1:25 does not imply that Joseph knew Mary after she had borne Jesus.
The Greek heôs, “until,” does not necessarily contrast “before” to “after.” It means that up to a certain moment, something happened or not, without considering what happened after that moment. For instance, the Greek text of the Septuagint says, in 2 Samuel 6:23, that “Mikal, daughter of Saul, had no children until (heôs) the days of her death.” This obviously does not suggest that she had children after her death. Matthew is interested in underlining that Jesus’ birth and conception were carried out without the intervention of any man.
Remove the word “until” from the verse, and you have the following:
“Joseph had no relations with her…she brought forth her firstborn”
Two simple statements. Protestants really disagree with the first of these two; therefore, the word “until” is the whole argument.
Either Joseph held off “until” and then proceeded to have relations (the Protestant position) OR Joseph had no relations with her. Period. (the Catholic position).
Naturally, Protestants argue for a simple reading of the text, but Catholics counter that “until” doesn’t actually imply the cessation of past action (namely, holding off). Although things look intuitively obvious for the Protestant point of view, in actual fact, the Catholic position is not harmed at all by the word “until” because that word implies nothing…and other verses in scripture PROVE that point (see below).
Consequently, Matthew 1:25 cannot be used to disprove the perpetual virginity of Mary.

Other Examples of “Until” That Do Not Require Cessation of Action
Genesis 8:7
The raven “did not return TILL the waters were dried up…” Did the raven ever return?
Deuteronomy 34:6 (Knox)
No one knew the location of his grave “until this present day” But we know that no one has known it since that day either.
1 Maccabees 5:54
“…not one of them was slain TILL they had returned in peace.” Were Judas Maccabeus and his troops killed when they returned?
Luke 1:80
“And the child grew and became strong in spirit; and he lived in the desert until he appeared publicly to Israel.” The Greek word translated “until” in this passage is heos, the same word used in Matthew 1:25. The child spoken of is John the Baptist who, after as well as before he appeared in public, resided in the desert (cf. Matt. 3:1, Mark 1:3,4; Luke 3:2).
Romans 8:22
“…the whole creation groans and labors with birth pangs together UNTIL now.” Is it still groaning?
1 Corinthians 15:25
“For He must reign TILL He has put all enemies under His feet.” After all enemies are put away, will Christ be reigning?
Ephesians 4:12-13
“…for the equipping…for the work of ministry… for the edifying…TILL we all come to the unity of the faith…” Once we become unified, will equipping, ministry, and edification still be necessary?
Hebrews 1:13
To which of the angels did God ever say, ‘Sit at my right hand until I make your enemies a footstool for your feet’”? After that time, the angels (or Jesus) could get up again?
1 Timothy 4:13
“Until I come, devote yourself to the public reading of Scripture, to preaching and to teaching.” After I arrive you won’t need to do any of those things?
1 Timothy 6:14
“…that you keep this commandment without spot, blameless UNTIL our Lord Jesus Christ’s appearing…” When Jesus comes back, we should disobey these commandments?
Revelation 2:25-26
“But hold fast what you have TILL I come. And he who overcomes and keeps My works UNTIL the end, to him I will give power…” Should we stop holding fast and stop obeying when Jesus returns?
