"49. One Law: Not only with respect to the eating of the paschal lamb is the stranger equal to the native Israelite, but also in the duty to observe all other commandments [Rashi]." pg. 399 of Soncino Chumash (edited by A. Cohen).
If A (material fact) then X (judgment).
If a Gentile is a covenantal member of Israel (A) then he or she is obligated to keep all the same mitzvot as a native Israelite (X).
- An example of tactic #1 is Derek Leman saying that One Law passages do not refer to all the mitzvot.
- Another example of tactic #1 is the assertion that "ger" in a One Law passage such as Exodus 12 can only be interpreted as referring to a circumcised convert (and thus cannot be used as precedent for the conclusion that uncircumcised male Believers are obligated to all the same mitzvot as a native member of Israel)
- An example of tactic #2 is to cite to Scriptural passages as evidence that Gentile Believers remain excluded from Israel.
