Commenting on whether the Ethiopian Eunuch was in fact a Jew or more likely a Proselyte.
First, Luke never indicated in Acts 8 that the treasurer from Ethiopia was a "Gentile." On the contrary, he implied that this eunuch was either a Jew or a proselyte when he stated that he had "come to Jerusalem to worship" (8:27). At this point in time, the eunuch was not yet a Christian; he had not yet heard and obeyed the Gospel. Thus, while he had in fact gone "to Jerusalem to worship," such worship was not with the church in Jerusalem. It seems obvious that the reason he was reading from the Old Testament book of Isaiah when Philip approached him, and the reason he already had traveled hundreds of miles from Ethiopia "to Jerusalem to worship," was because he was either a Jew or (more likely) a proselyte. On the possibility of the eunuch being a Jew, respected biblical scholar J.W. McGarvey stated
"It was not uncommon for Jews born and reared in foreign lands to attain to eminent positions, such as this man enjoyed, and especially in the department of finance.."

If the Eunuch wasn't a Jewish convert or even born into Judaism, then explain how he came to have in his hands a copy of the scroll of Isaiah, which non-Jews were forbidden from having according to Jewish Law? It's obvious, he was either a Jew by birth or by conversion.
How's that BoTR?
