The Rebbe said:<ref>Based on [http://www.sichosinenglish.org/books/chassidic-dimension-2/08.htm Likkutei Sichos Vol. XV, pp. 289-292]</ref>
:One of the Halachic differences between these two opinions is the age at which a non-Jew becomes obligated to observe the Seven Noahide Laws.
:If the obligation of mitzvos at the age of 13 is dependent on the age at which (most) people reach maturity, then it should apply to Jew and non-Jew equally. If, however, it is one of the supra-rational Laws of Measures - which do not apply to non-Jews - then the age at which non-Jews' are obligated to perform their seven commandments depends entirely on individual maturity.
:In terms of spiritual service, the difference between these two opinions relates to the manner in which a Jew is to approach the performance of Torah and mitzvos:
:According to the first opinion, the approach is one of serving G-d logically; if the age at which one becomes obligated to perform mitzvos depends on one' intellectual maturity, it is understandable that the service commences with logic and comprehension.
:According to the second opinion, however, the obligation to begin performing mitzvos at 13 is supra-rational - because G-d has so commanded. It therefore follows that the approach to the performance of mitzvos involves the supra-rational acceptance of the Divine Yoke.
