יורה דעה קכ״דYoreh De'ah 124

Se’if 1א׳

תִּינוֹק גּוֹי שֶׁאֵינוֹ מַזְכִּיר עֲבוֹדַת כּוֹכָבִים וּמְשַׁמְּשֶׁיהָ, אֵינוֹ אוֹסֵר יַיִן בְּמַגָּעוֹ, אֶלָּא בִּשְׁתִיָּה.

A gentile child who does not make mention of idolatry and its appurtenances does not render wine forbidden by his touch, save for drinking.

Se’if 2ב׳

גֵּר תּוֹשָׁב, דְּהַיְנוּ שֶׁקִּבֵּל עָלָיו שֶׁבַע מִצְווֹת, וְכֵן גֵּר שֶׁמָּל וְלֹא טָבַל, מַגָּעָן אוֹסֵר בִּשְׁתִיָּה. הַגָּה: וְכָל זְמַן שֶׁלֹּא טָבַל כָּרָאוּי, מִקְרֵי לֹא טָבַל (ר"ן פ' הַשּׂוֹכֵר וְהַגָּהוֹת מָרְדְּכַי דִּיבָמוֹת פֶּרֶק הַחוֹלֵץ). וְיֵשׁ מְקִלִּין אֲפִלּוּ בְּמַגַּע גֵּר תּוֹשָׁב (טוּר בְּשֵׁם הָרֹא"שׁ וְתוס' וּמָרְדְּכַי), אֲבָל יַיִן שֶׁלּוֹ וַדַּאי אָסוּר (בֵּית יוֹסֵף).

A ger toshav — that is, one who has accepted upon himself the seven commandments — and likewise a convert who was circumcised and did not immerse: their touch renders it forbidden for drinking. Hagah [Rema]: And so long as he has not immersed as is fitting, he is called one who has not immersed (Ran, chapter "One who hires", and Hagahot Mordechai on Yevamot, chapter "He who performs chalitzah"). And there are those who are lenient even in the touch of a ger toshav (Tur in the name of the Rosh, and the Tosafot, and Mordechai); but his own wine is certainly forbidden (Beit Yosef).

Se’if 3ג׳

הַלּוֹקֵחַ עֲבָדִים מֵהַגּוֹיִים וּמָלוּ וְטָבְלוּ מִיָּד, אֵין מְנַסְכִין; וְיַיִן שֶׁנָּגְעוּ בּוֹ, מֻתָּר בִּשְׁתִיָּה, וְאַף עַל פִּי שֶׁעֲדַיִן לֹא נָהֲגוּ בְּדָתֵי יִשְׂרָאֵל וְלֹא פָּסְקוּ שְׁמוֹת אֱלִילִים מִפִּיהֶם.

One who buys slaves from the gentiles, and they were circumcised and immersed at once — they do not pour libations, and wine that they touched is permitted for drinking, even though they have not yet conducted themselves by the laws of Israel and the names of idols have not ceased from their mouths.
