As I prepared to pitch this piece, I hesitated slightly to add just one more voice to the online firestorm of opinions and analysis of the recent Massachusetts Commonwealth vs. Lindsay Clancy case. There has been a lot of focus on whether Clancy was guilty without a reasonable doubt and a lot of analysis of her specific actions leading to and after the acts of violence she committed. I have even seen Christians discussing the potential spiritual disruptions or conditions that may or may not have been present in her life. People have a lot to say.
However, there is an element to this case that has often been overlooked. I was pulled into the live airing of the case at a point where therapists and mental health professionals were giving testimony about Clancyโs relative mental health during the period of her decline. During and around the witness testimony that was centered around mental health there was a pivotal moment in the case as it pertains to faith and religious rights, and it should make Christiansโand all religious peopleโbreathe a sigh of relief.
Two Religious Missteps
There were two big moments in the trial where religion took center stage. During the prosecutionโs questioning of Lindsay Clancyโs mother, Susan Clancy, there was a moment when the prosecutor, Jennifer Sprague, reached a point in her questioning where she decided to ask Mrs. Clancy if she was a Catholic. Susan Clancy confirmed and then, subsequently, the prosecutor returned with the question, โSo youโre aware that murder is considered a mortal sin?โ This question immediately prompted the defense attorney to object, and the judge, after sustaining the objection, went even further to state to the jury that they must completely disregard the reference to sin and religious affiliation. This was misstep number one by the prosecution.
Misstep number two happened when a separate witness for the prosecution very blatantly, in reference to things Clancy was purported to have said during her violent crime, again brought up the issue of mortal sin in reference to Catholic theological dogma and her personal religious affiliation. This enraged the judge to the point of quickly sending the jury out of the room and reprimanding the prosecution for allowing two references to Clancyโs religious convictions. Although the defense failed to secure a mistrial on this basis, the jury was then forcefully instructed by the judge to disregard the testimony about religion and that it has no place in the courtroom.
The โWhyโ: Federal Rule 610
But why? Why is it improper to discuss such issues in the courtroom and why did the judge get so worked up?
Enter Federal Rule 610.
According to the Federal Rules of Evidence, โEvidence of a witnessโs religious beliefs or opinions is not admissible to attack or support the witnessโs credibility.โ This straightforward statement has protected scores of individuals and, subsequently, religious institutions from juries considering religiously biased evidence.
The American court system is built on a foundation to exclude harmful religious testimony from affecting individuals who are accused of crimes, from the most petty to the egregious. These protections link back as an extension of our Constitutional rights enshrined in the First Amendment of the Constitution. Freedom of religion is a lofty notion; it takes small but significant steps at every level of government to make a foundational principle a reality for an entire nation. As individual beneficiaries of the work done to establish a society free from many forms of discriminatory practices, we as Christians may have the most to be thankful for when it comes to the law and the reaction of judges to uphold such statues.
The Reminder
In the midst of a high-profile case like the Clancy case it serves each of us to remember the big picture of how our court system is actually serving all of us. Clancyโs religious rights are the same for you and for me. Gratitude for equal protection should be at the forefront for us all. Our system, unlike many throughout the world, has rules that are made based on precedent and is designed to eliminate bias. This provides a sense of security that is hard to come by.
Therefore, in the midst of a difficult caseโand in the conversations being had in its aftermathโmay we be thankful for a system designed for the people, and equal thanks for the people who do the daily work of maintaining its integrity. None of us know what the ultimate outcome of the Clancy case will be, but we do know it wonโt be decided based on her personal religious affiliation.
Hung jury or not, that is good news for all American Christians.







Thank you, Landon, for clarifying this. I was wondering.
