Question

A gentile who chooses to be buried in the Land of Israel.
Although the teaching in the Talmud that one who is buried in the Land of Israel has his sins forgiven is learned from the juxtaposition of “and He will atone for His land, His people” and “an altar of earth you shall make for Me” — earth, earth. And a gentile, seemingly, is not included in “His people.”
But the language of the Talmud is “anyone,” and likewise in Maimonides they did not limit it specifically to Jews.
And this altar is seemingly universal, since a gentile too can bring an offering to God on the altar, and offerings are brought in his name.
(Although the distinguished scholar Y.Y.P. noted to me that this is only for a voluntary offering, but a gentile has no sin-offering and no atonement through the altar.)
And also in the Maharsha on Ketubot, where the idea is that Adam’s dust was gathered from beneath the altar, and one who is buried in the Land of Israel (the entire Land of Israel is like being beneath the altar for this purpose) essentially returns to the dust from the place where he was created, and that is an advantage and brings atonement. Again, this is a universal advantage, not specifically for Jews.
 
So then, are a gentile’s sins forgiven when he is buried in the Land of Israel, just like a Jew’s — or not?
