Any young couple can go into marriage with intentions we don't know, and the priests are supposed to screen them these days.
Jesus never said anything about a marriage being invalid except "in the case of fornication/adultery". And he didn't put it in those exact terms with the word invalid, but the implication was the marriage was defective.
And this is WHY Jesus was NOT married:
There were NONE that could pass Mary's requirements!
Oy Vey!!
If Jesus was a doctor; maybe; but he's The SON of GOD!!!
The term "JAP" and the associated stereotype gained attention beginning in the 1970s with the publication of several non-fiction articles such as Barbara Meyer's Cosmopolitan article "Sex and the Jewish Girl" and the 1971 cover article in New York magazine by Julie Baumgold, "The Persistence of the Jewish Princess".[53] "JAP" jokes became prevalent in the late 1970s and early 1980s.[54][55] According to Riv-Ellen Prell, the JAP stereotype's rise to prominence in the 1970s resulted from pressures on the Jewish middle class to maintain a visibly affluent lifestyle as post-war affluence declined.[50][56] The concept was the butt of jokes and spoofed by many, including Jews.[57]
The stereotypical subject, as described in these sources, is over-indulged by her parents with attention and money, resulting in the princess having both unrealistic expectations and guilt, accompanied by skill in the manipulation of guilt in others, resulting in a deficient love life.[53] The stereotype has been described as "a sexually repressive, self-centered, materialistic and lazy female,"[58] who is "spoiled, overly-concerned with appearance, and indifferent to sex", the last being her most notable trait.[54][55]
These "exception clause" passages in Matthew 5 and 19 do not apply to a Catholic marriage. They apply only to a Jewish marriage, and then only apply to the phase translated as betrothal.
