The Ethiopian official continued his journey “rejoicing,” a remark that reflects the reality of his faith in Jesus as Israel’s Messiah and the Savior from sins, implying that he had received the Holy Spirit; the present participle (χαίρων) suggests a permanent reality of his commitment to Jesus. Irenaeus and Eusebius relate that the converted eunuch was the first missionary to Ethiopia.2017
