The Canon Law Society of America (CLSA) publishes annually Roman Replies and CLSA Advisory Opinions for canonists and those seeking a clearer understanding of the praxis legis of the Catholic Church. The combination of these two services, begun in 1984, continues to serve as useful resources for those involved in the application of canonical discipline. The compilation of materials for Roman Replies 2023 was guided by Donna Miller, Executive Coordinator of the CLSA and an ex officio member of the CLSA Publications Advisory Board (PAB). The collection of entries in this issue, when viewed in conjunction with previous volumes, assists the reader both in understanding recent developments in the law and in identifying current trends in the praxis of the Roman Curia. The selection, editing, and assembly of opinions for CLSA Advisory Opinions 2023 were provided by Monsignor Michael A. Souckar, chair of the Publications Advisory Board, and Reverend Patrick M. Cooney, OSB, a member of the Publications Advisory Board. Editorial assistance was provided by the CLSA Executive Coordinator. This year, we have introduced ad experimentum a division into two sections of the advisory opinions that were received. The first section includes the traditional style of opinions that are shorter and more focused. In the past, these opinions have rarely exceeded eight pages. The second section contains lengthier “opinions,” some of which are akin to position papers or theses. Because the CLSA does not have a venue for members to share writings of this nature, we decided this year to include these as a second section of advisory opinions. They have not been peer-reviewed, which would be required for publication in a more formal setting. The topics addressed in the opinions of both sections reflect a variety of canonical issues and demonstrate the scope of canonical expertise and reflection by members of the Society. The opinions are those of the authors, and their publication here does not imply endorsement by the CLSA Board, Staff, or Membership.
