Ford K. Brown wrote that Wilson "probably made heavier contributions and subscriptions to moral and reforming societies of the day than any other person with the possible exception of
Wilberforce. He was involved with 36 societies.
Baptist Missionary Society Wilson was Treasurer of the London
Baptist Missionary Society from 1826 to 1834. Of the original
Serampore Trio,
William Ward had died in 1823;
Joshua Marshman came to the United Kingdom in June 1826. In negotiations that became known at the time as the Serampore controversy, he represented the missionaries. There are accounts of the negotiations given by
John Foster, a supporter of Marshman. The controversy was carried on in public from 1828. By 1831 Samuel Hope (1760–1837), a Liverpool banker and the mission's home treasurer, had offered to act as an arbitrator in the disputed matters. The context was a letter of March 1830 from Marshman, his son
John Clark Marshman and William Carey, proposing an arbitration committee of six, naming Hope plus two others to be chosen on their side, and Wilson with two others to act for the Society. John Clark Marshman wrote later that Wilson was thought by the Serampore side "a man devoid of all jesuitism or diplomacy, and in whose justice and impartiality they felt great confidence." On the Council of the Society, Wilson was in a
dovish group including also
Olinthus Gregory, Joseph Gutteridge (1752–1844),
Joseph Ivimey and
Benjamin Shaw. On the financial matters in dispute, they took the view that some dependence of missions on the home organisation was to be expected. Wilson chaired a meeting of the Society's Council in February 1831 objecting to continuing campaigning by the mission's supporters. That year Ivimey published
Letters on the Serampore Controversy, dedicated to Wilson and addressed to
Christopher Anderson. A comprise solution to the Serampore situation was reached only in 1837, after the deaths of a number of the principal figures.
Religious Tract Society Wilson was Treasurer of the
Religious Tract Society from 1827 to the end of his life. Interested in reprinting works of the English Reformers in others, he paid for
stereotype plates for works published by the Society, and donated those, as well as bequeathing a sum in
Consols. ==Benefactor==
