Josephus, The Jewish War
[The Antiochian Jews] were constantly attracting to their religious ceremonies multitudes of Greeks, and these they had in some measure incorporated with themselves. But no one need wonder that there was so much wealth in our Temple, for all the Jews throughout the habitable world, and Yirei HaShem, even those from Asia and Europe, had been contributing to it for a very long time.
Rabbi Tzvi Peres Chayes, Cheif Rabbi of Vienna, 1921
This is a clear proof, supporting what we know from Jewish-Hellenistic literature, that these PartialGentiles had a reserved section in the temple, apart from the sections for Israelites, Levites and Priests. This is a clear proof that they are not part of Israel but are foreigners, partial converts, who are Jewish according to the essence of their faith, and therefore present for Jewish worship
Mekhilta D'rebbe Yishmael, Exodus 22:20
One shall say: 'I am the L rd's'; another shall call in the name of Yaakov; another shall mark his arm 'of the L rd'; and in the name of Israel he shall be called": "I am the L rd's" — these are the fearers of Heaven, untainted by sin. "another shall call in the name of Yaakov" — these are the minors (who died in childhood), the sons of the wicked in Israel. "another shall mark his arm 'of the L rd'" — these are the penitents. "and in the name of Israel he shall be called — these are the righteous strangers (i.e., the proselytes).
When Sarah gave birth to Isaac the nations of the world mocked her saying ‘He is the son of a servant and she pretends to be nursing him. At that time Abraham told Sarah ‘this is not a time for modesty. Present yourself for the sanctification of God’s name. Sarah exposed her breasts and milk came pouring out like springs of water as it is written there (Gen. 21) ‘Who would have told Abraham, Sarah would suckle sons.’.. The nations of the world brought their children to Sarah for breastfeeding...All converts in the world who join the Jewish community and all those who are Yirei HaShem in the world are from those who sucked from Sarah’s milk, hence it is written ‘The mother of the children is joyful.’ (Psalm 113) - this is Sarah
Yechaveh Da'at 4:55 (Rav Ovadia Yosef)
The sages forbade eating the bread of gentiles and idolaters. It seems that the gentiles in our lands who are Muslims and do not worship idols, it is permitted to eat their cooked foods and their bread, and so it seems from the words of the Sheikh, who noted what it says in Section 124:12, that Muslims render wine forbidden only for drinking, not for deriving benefit. What he means to say is that wine used for libations by idolaters is forbidden for drinking and deriving benefit, so the wine of Muslims is one level lower. If so, with their bread and cooked foods, which would ordinarily be forbidden only for eating, if they are not idolaters it is completely permitted.
Yabia Omer 5:10
The entirety of the prohibition against eating gentile bread is because of a concern about seclusion with a gentile woman, and [the concern about] seclusion with a gentile woman is in order to distance oneself from her idolatry. If this is so, it is clear that the decree [about bread] refers specifically to gentiles who perform idolatry, and not regarding gentiles who do not perform idolatry. If so, we have no reason to forbid the bread of Muslims, who disavow idolatry and hate idol-worshippers, and there is no decree about them.
Shulchan Ha'ma'arechet (Rabbi Yitzchak Yosef, son of Ovadia Yosef, current Sephardic cheif Rabbi of Israel)
Kiddushin are not effective with a non-Jewish woman, because it is written “do not make marriages with them [for doing so will turn away you son from following Me, that they may serve other gods].” But with a ger toshav woman, since there is no prohibition of “do not make marriages with them” [because they do not serve other gods], kiddushin are effective.
Rabbi Avigdor Nebenzahl (Israeli Orthodox Rabbi)
We find (Ruth 4:10) that the biblical Ruth, the wife of Mahlon, even when she was with him still had not converted. And it seems that she was a ger toshav, and so the law of marriage from “and he shall cling to his wife” applies, and so she was not included in the category of those who tempt [towards idolatry], even though the hold of Jewish kiddushin did not apply to her.
