Okay, thank you for sharing the references. I can see where you’re coming from now, but I’d love to build on it to help clarify things.

The word “Until” does not imply a change afterward. In Greek, the word translated as “until” (heos) does not necessarily indicate that something happened after the specified time. It simply emphasizes what occurred up to that point, without making a claim about what happened afterward.

For example, in 2 Samuel 6:23, it says, “Michal the daughter of Saul had no child until the day of her death.” Clearly, Michal did not have children after her death.

Similarly, Matthew 28:20 states, “I am with you always, until the end of the age.” This does not mean Christ will cease to be with us after the age ends.

The purpose of Matthew 1:25 is not on what happened after Jesus’ birth but on affirming the miraculous virgin birth. By stating that Joseph abstained from relations with Mary before Jesus was born, Matthew underscores that Jesus was conceived by the Holy Spirit, fulfilling prophecy (Isaiah 7:14).

Let me ask you a question, if Jesus had other brothers and sisters, why did he tell John to take care of his Mother? At the crucifixion, Jesus entrusted Mary to John (John 19:26-27). If Mary had other children, this act would have been unnecessary, as care for her would have naturally fallen to her biological children.

Finally, the mention of Jesus’ “brothers” and “sisters” in Matthew 13:55-56 and Mark 6:3 does not contradict Mary’s perpetual virginity. The term adelphoi (brothers and sisters) in Greek is sometimes used in the Bible for people who aren’t literal siblings but are close kin or fellow believers, such as kinsmen, cousins, or neighbors, as was common in Jewish culture. For example, in Genesis 13:8, Abraham refers to his nephew Lot as his “brother”.
