In a previous post, I was given an answer which mostly works very well.
\NewDocumentCommand{\datefeast}{mm}{% \par \noindent \makebox[0pt][l]{#1.}% \makebox[\textwidth]{\Large #2.}% } However, I finally ran into the one drawback: the text is now long enough to over-print the number. See this.
I'm planning on abbreviating where possible, but there aren't really conventional abbreviations in this case, not for "Sacrorum Stigmatum" at least.
I need it to do this, preferably with the first line longer than the second as shown.
