The following is a quote from that article.
“Ma’asim” (mah-ah-seem): “Acts or deeds that serve as precedents or laws of standard behavior”—
like the wearing of the sun disc hat (kippah) and lighting of Shabbat candles with the prayer that
says: “Blessed are you, King of the universe, who has commanded us to light the Shabbat candles”.
Come on now folks, did Yahuweh command us to light candles on Friday night? -- NO! Did He teach
us to have a special type water container filled with water, and then pour the water over the right
hand, then the left hand, repeating that two or three times, in order to please Him? NO!”
The Halacha includes the principle of Ma'asim “works or deeds”. The principle works like this...
If a certain high level Zadik/rabbi does something in his life as a habit or custom then we should follow his lead and do what he is doing. We are to take that rabbis life as an example on how to live our own lives. Lets find out if the NT teaches us this principle.
2 Thessalonians 3:7-9 “For you yourselves know how you ought to imitate us, for we are not disorderly among you...not because we do not have authority, but to make ourselves an example for you to imitate.”
In addition to all the times that the NT tells us to follow or imitate the works of rabbi Yeshua, we have this verse telling us that we are to imitate or follow the ma'asim of rabbi's Shaul, Sila, and Timothy.
Here is another concern raised in that article.
The Commandments of Rabbis: “By observing the rabbis’ commands, you are obeying God”.
From the Midrash Pesikta Rabbi: “A person must not say `I will not keep the commandments of the
elders because they are not from the Torah’. The Almighty says to such a person, `No my son!
Rather, all that they decree upon you observe! As it is written: “According to the instructions which
they teach you” (Deuteronomy 17:11). `Even I (Yahuweh) must obey their decree as it is written
`you will decree and I (Yahuweh) will fulfill it’”.
The authors concern can be broken into two parts
1 – Do rabbi's have authority to issue commands?
2 – Whose word do we listen to, a heavenly beings or our Rabbi's? Who has the received authority to be obeyed?
Lets deal with the first concern by referring to the 2 Thessalonians once again.
2 Th 3:4-14 “And we trust in the master as to you, both that you do and shall do what we command you...but we command you, brothers, in the name of the master Yeshua messiah, that you with draw from every brother who walks (Halacha – having a different Halacha) disorderly (without the siddur – siddur means order) and not according to the tradition (Note that he said traditions and not written Torah only) which you received (a tradition that must be handed down and not made up) from us (your rabbis)...For even when we were with you, we commanded you this: If anyone does not wish to work, niether let him eat (this command is not in the written Torah as such)...and if any does not obey our word (the word of your rabbi) in this letter, note that one, and do not keep company with him, so that he is put to shame.”
There, the issue is dealt with, rabbi's have authority to make commands and we have to follow them. Period.
And the second concern can be addressed in...
Galatians 1:8 “However even if we, or a messenger out of heaven, bring a good news to you beside what we have announced to you, let him be accursed...For I did not receive it from man, nor was I taught it, but through a revelation of Yeshua Messiah.”
Rabbi Shaul states that even if a heavenly being (it does not say a fake heavenly being, its refering to A REAL ONE) comes to you and tells you something different than what Rabbi Shaul told you then don't listen to the heavenly being listen to your rabbi...Shaul.
