Ambrosiaster

SBL Press has clarified its guidance about citing J.-P. Migne’s Patrologia Latina based on the discovery that various year’s printings of certain volumes within Patrologia Latina have differences. Among these differences are variations in the column arrangements for the texts contained in Patrologia Latina. The Press’s initial recommendation was that

authors always check a PL volume title page to ensure that the printing is dated 1865 or earlier. If the publication or printing date is 1868 or later, we encourage authors to find an earlier printing of PL to cite.

There are a pair of references in Cranfield’s ( affiliate disclosure) and Moo’s ( affiliate disclosure) Romans commentaries to comments by Ambrosiaster about the origin of the Christian community in Rome, and I’ve been curious to give this reference a look. Both authors cite the reference as found in J.-P. Migne’s Patrologia latina, vol. 17, col. 46 (Cranfield, xiii, 17n2; Moo, 4n7).

My go-to index for online PDFs from Migne’s Greek or Latin patrologies is Documenta Catholica Omnia. The index for PL, vol. 17, indicates that cols. 45-184A are Ambrosiaster’s commentary on Romans. Clicking through to the archived PDF, however, I noticed the first column in the document was col. 47. The Latin quotation as excerpted by Cranfield occurs in col. 48 (not 46, per Cranfield’s and Moo’s citations).
