[aMorePerfectUnion]

Did you notice the Greek word was for adultery is in the passage, and not for the exception ? Adultery is specified as the result of divorce and remarriage, not as a valid excuse to do it. Adultery is not fornication (porneia).

This statement is absolutely a false reading of the Greek language and Scripture.

[imardmd1]

Correct, AMPU. Adultery, the union of two humans according to God’s plan for their bodies, is but a subclass of the more general term pornaya = sexual immorality of all kinds.

False

The statement is not "absolutely a false reading of the Greek language and Scripture."

Neither the Gospel of Mark, nor the Gospel of Luke, mention any exception to the rule that a sanctified (by God) marriage cannot be undone by divorce and any remarriage is adultery. The Gospel of Matthew alone mentions an exception, "saving for the cause of fornication" or "except it be for fornication." This case can be seen in the Gospel of John in the the Pharisees accusation that Jesus was "born of fornication." They supposed his mother Miriam/Mary had porneia before she and Joseph were joined in marriage (since she showed up pregnant, which explains why Joseph considered privately divorcing her. Therefore the exception for porneia was quite limited and does not extend to general adultery after a marriage which God has sanctified (God has joined together). That is why the exception does not use the Greek word moixeía. It is intended for marriages in the betrothal period that would not go forward and be completed as "what God has joined together."

• Now the birth of Jesus Christ was on this wise: When as his mother Mary was espoused to Joseph, before they came together, she was found with child of the Holy Ghost.
• Then Joseph her husband, being a just man, and not willing to make her a publick example, was minded to put her away privily.

• Ye do the deeds of your father. Then said they to him, We be not born of fornication; we have one Father, even God.
• Jesus said unto them, If God were your Father, ye would love me: for I proceeded forth and came from God; neither came I of myself, but he sent me.
