With this in mind, it seems to me that many of the mosaic laws, that were not fulfilled by Jesus Christ, still apply.
Nothing of the Old Law was left unfulfilled by Our Lord. What aspect of the Mosaic Law could possibly not have been sufficiently fulfilled by the Sacrafice of Calvary, which was the very Event that all of the Old Law was designed to point toward?
I'm also considering that these laws may only apply to those descended of the Israelites since they were a covenant between God and the Israelites only.
Am I wrong?
Yes. Exceedingly so.
Look to how the Church, through the Inquisition, dealt with the Marranos, who were doing just what you're suggesting here.
As Ladislaus says, the abolishment of the Mosaic Law is de Fide. The continued practice of Mosaic dietary restrictions among Catholics of Jєωιѕн stock in the Patriarchate of Jerusalem in the first and second centuries (which, amazingly, still survives as one of the many corrupt and degenerate practices of the backwards Eritrean schismatics) was merely a disciplinary expediency respecting long held cultural practices for the sake of unity. If you find yourself running afoul of any putative "Catholics" calling for a return to this practice, get as far away from them as you can. We ought to know better than anyone the disastrous results of liturgical and disciplinary primativism, especially when it's put in service of an "ecuмenical" (read: Judaizing) agenda.
I was thinking about these particular types of mosaic laws:
Not to reap the entire field (Lev. 19:9; Lev. 23:22)
To leave the unreaped corner of the field or orchard for the poor (Lev. 19:9)
Not to gather ol'loth (the imperfect clusters) of the vineyard (Lev. 19:10)
To leave ol'loth (the imperfect clusters) of the vineyard for the poor (Lev. 19:10; Deut. 24:21) (affirmative) (CCI3).
Not to gather the peret (grapes) that have fallen to the ground (Lev. 19:10) (negative) (CCI9).
To leave peret (the single grapes) of the vineyard for the poor (Lev. 19:10) (affirmative) (CCI4).
Not to return to take a forgotten sheaf (Deut. 24:19) This applies to all fruit trees (Deut. 24:20) (negative) (CC10).
To leave the forgotten sheaves for the poor (Deut. 24:19-20)
How might you explain Christ fulfilling these?
