Pioneer people are too intent on maintaining life to go into the abstrusities of either ethics or theology. Wesley soon saw that his powers demanded a wider field. The experience, though, had done him much good, especially in two ways. He had gotten a glimpse of chattel slavery and made a remark about it that is forever fixed in literature, "Human slavery is the sum of all villainies." Then he had met on shipboard a party of Moravians, and was so impressed by them that he straightway began to study German. In six weeks' time he could carry on an acceptable conversation in that language. At the end of the two years which he spent in Georgia, through attending the services of the Moravians, he could read, write and preach in the German language. The Moravians seemed to him the only genuine Christians he had ever seen, and their example of simple faith, industry, directness of speech, and purity of life made such an impress upon him that thereafter Methodism and Moravianism were closely akin. At Savannah there were some people too poor to afford shoes, and when these people appeared at church in bare feet they were smiled at by the alleged nobility. Seeing this, on the following Sunday, John Wesley appeared barefoot in the pulpit, and this was his habit as long as he was in Georgia. This gave much offense to the aristocrats; and Wesley also made himself obnoxious by preaching salvation to the slaves. Indeed, this was the main cause of his misunderstanding with the Governor. Oglethorpe considered any discussion or criticism of slavery "an interference with property-rights." And so Wesley sailed back to England, sobered by a sense of failure, but encouraged by the example of the Moravians, who accepted whatever Providence sent, and counted it gain. The overseers of Oxford, like Oglethorpe, had no special personal sympathy with the peculiar ideas of Wesley; but as a matter of policy they recognized that his influence in the great educational center was needed for moral ballast. And so his services were secured as Greek Professor and occasional preacher. Concerning the moral status of Oxford at this time, Miss Wedgwood further says:
