Most of the other stuff you listed is not forbidden halachically as far as I know – reading from siddur is certainly not forbidden neither is praying together (you do this when visiting a synagogue anyway), observing Shabbat in the manner that you do (since it’s safe to assume that you are not observing it in a strict manner, therefor you would not be considered (by traditional authorities at least) as observing it JEWISHLY (which technically means – again, from traditional point of view – that you are NOT observing it at all!), lighting candles, etc. Speaking about lighting candles – a Jew must light Shabbat candles for him/herself – that is if circumstances allow to light them in the first place. If he/she can’t or missed the time to light them, there’s always next Shabbat. So, technically speaking you lighting them is for your personal benefit – it doesn’t fulfil the commandment (from a halachic point of view).
So, aside from tefillin, I don’t remember reading about any of this as being forbidden to non-Jews.
Gene Shlomovich from his comments on
Book Review: Tefillin, A Study of the Commandment of Tefillin
The link I just posted above leads not only to Gene's comments, but to a book review I just wrote about a new First Fruits of Zion (FFOZ) booklet about the history and commandments involving the use of Tefillin in Jewish (and possibly Gentile) prayer (and please feel free to read the review and comment about it on my other blog).
Gene's comments started me wondering about a subject that sometimes occurs to me when we have these conversations. Messianic Judaism, and particularly that expression that takes to heart the concept of Bilateral Ecclesiology (BE), tends to believe that the specific roles and responses of Jewish and Gentile disciples of the Messiah are different based on having a different status before God. From that perspective, authoritative rulings are not only rendered in the written Torah, but also in the Oral tradition and judgments of the learned Jewish sages. Halachah, as Gene mentions, is considered applicable to define both Jewish and Gentile responsibilities (or lack thereof) relative to what we think of as traditional Jewish religious practice.
One of the criticisms that Messianic Judaism has of the One Law and Two-House movements, is that these groups only consider the written Bible (Torah, Prophets, Writings, and Apostolic Scriptures) as authoritative and relegate the Oral law and rulings of the sages to the status of "opinions", which are then easily dismissed. This is why, for example, that a One Law practitioner can say they are keeping a type of kosher by only eating beef, chicken, and vegetables purchased at their local supermarket, while a Messianic Jew whose practice is more "rabbinically" centered, would require that their kosher meat be certified as such under rabbinic supervision, prepare their food in a kosher kitchen, not mix meat and dairy products, and so forth. Hamburger from Safeway or Albertsons just wouldn't do and a cheeseburger is out of the question.
As Gene formerly pointed out in the book review and as other comments there illustrate, the majority Jewish opinion would forbid a non-Jew from observing the Sabbath "Jewishly" and would forbid men from, among other things, praying while wearing a tallit and tefillin. While the rabbinic rulings are not unanimous, if a non-Jew were to walk into their local (non-Messianic) synagogue and ask the Rabbi what he or she thought of Christians wearing tzitzit and laying tefillin, it is very likely the Rabbi wouldn't support such activities.
But they don't believe that Yeshua is the Messiah either, and thus don't consider any of his teachings authoritative. Neither did any of the Jewish sages including Rambam, whose statements quoted in my book review could be interpreted as supporting Gentiles obeying more than the Seven Noahide Laws.
Halachah, in part, must make the assumption that all non-Jews are obligated only to the Noahide Laws, and a Gentile's responsibilities to God are contained within those limitations (and keep in mind that the seven laws can be further subdivided into multiple, specific behaviors).
Are non-Jewish people who have come to faith in the Jewish Messiah and who have become the Messiah's disciples (you can't get around Matthew 28:19-20) considered absolutely equivalent to Noahides? Is the Jerusalem letter (Acts 15) considered to be a specific and limiting container for Gentile Messianic disciples in precisely the same way as the Noahide Laws recorded in Genesis 9?
I've previously blogged that I don't believe the Acts 15 letter describes an absolute limit for Gentile Messianics, since Yeshua's teachings that we Gentiles are required to obey extend beyond the borders of the letter and into many principles directly drawn from the Torah mitzvot (visiting the sick, feeding the hungry, remaining faithful to one's spouse, not murdering, and so forth).
Everything hinges on the difference (assuming there is one) between the status of a Gentile Noahide and a Gentile Messianic disciple before God. The "requirements" are different for both groups and at least from what I can see. Gentile Messianic disciples are allowed, and perhaps required, based on the two greatest commandments from Matthew 22:37-40 (which are derived from Deuteronomy 6:5 and Leviticus 19:18) to have a love for God not suggested by the Noahide commandments. I've never gotten the impression that Noahides would ever have the ability to "approach the Throne of God", at least in the same manner as those of us who are supposed to be fellow heirs (Ephesians 3:6).
I don't have an answer to this next question, but can we totally accept all of the halachah regarding Gentile religious practice, when every single ruling was written specifically for Gentiles who were either Noahides or pagans?
Wait! What did I say?
Gentiles have two classes...or three?
Consider this. We non-Jews in the movement are disciples of the Jewish Messiah, AKA "Christians". A concept and status not taken into account (for the most part) in halachah (and when it is taken into account, the "account" is usually not favorable, given the historic relationship between Christians and Jews). However, does any of the rabbinic judgments consider the difference between a "righteous Gentile" and a pagan (a Gentile who does not comply with the Noahide requirements)? They would have to if the status of "Noahide" were to have any meaning. But if Christianity and Messianic Judaism (in all its forms and variations) must accept the fact, based on the Matthew 28, that Gentiles are also able to assume the status as "disciples of the Jewish Messiah" and heirs according to the promise (Galatians 3:29), then there must be a difference between Gentile Messianics and Gentile Noahides. Otherwise, why not just have all Gentiles either convert to Judaism or become Noahides and leave it at that? Heck, Yeshua could have saved himself a lot of trouble if he didn't have to die for the sins of the world (John 3:16).
Like I said before, I don't have the answer to these questions, but these are questions we don't ask very often, if at all. I believe that, in some manner or fashion, we have to consider the possibility that halachah for Gentile Messianic believers may need to be "adjusted" to accommodate a status for us that the sages, by definition, would never have considered.
The road is long and often, we travel in the dark, ignoring the light of the world. Look for the lamp who lights your path or you may become lost in the dark forever.
