The Massachusetts law against discrimination (MGL Title XXI, Ch. 151B, Sec. 1(5)) provides:
[N]othing herein shall be construed to bar any religious or denominational institution or organization, or any organization operated for ... educational purposes, which is operated, supervised or controlled by or in connection with a religious organization, and which limits membership, enrollment, admission, or participation to members of that religion, from... taking any action with respect to matters of employment, discipline, faith, internal organization, or ecclesiastical rule, custom, or law which are calculated by such organization to promote the religious principles for which it is established or maintained.In its press release on the case, GLAD says: "Our laws carefully balance the important values of religious liberty and non-discrimination. When Fontbonne Academy fired Matt from a job that has nothing to do with religion, they came down on the wrong side of the law."
