Plagiarism
In 2018
P&R Publishing withdrew Derek Thomas' commentary on the
Book of Acts after allegations of uncredited use of pastor
Sinclair Ferguson's
sermons on Acts. They noted that "the lack of attribution resulted from unclear note-taking more than a decade before the commentary on Acts was written, and we believe it does not reflect intentional misuse on the part of the author."[3]
The church leadership at Thomas' church backed Thomas in a statement of support.[3] Reformed Theological Seminary, which Thomas works for as a professor, also defended him, saying, "an RTS committee reviewing the Acts incident had cleared Thomas of 'any knowing and intentional plagiarism.' He [Ligon Duncan] added that Thomas will continue to teach. 'From the standpoint of RTS,' Duncan wrote, 'the case is now closed.'"[3]
A commission of the
Associate Reformed Presbyterian Catawba Presbytery found that Derek Thomas had in fact copied from the sermons of Sinclair Ferguson without proper attribution, but that
"none of the interviews and investigations of this Committee have revealed any credible evidence that Derek Thomas intentionally engaged in the practice of plagiarism." Accordingly, Thomas was admonished in writing by the Catawba Presbytery for "unintentional plagiarism".[4]
