The Scripture says, “Therefore, brethren, stand fast and hold the traditions which you were taught, whether by word or our epistle” (2 Thess. 2:15). Obedience to this command requires that we make a distinction between two kinds of traditions: 1) the autonomous traditions of men that subvert the truth by means of the twin practices of “Solo” Scriptura (in contrast to Sola Scriptura) and Qualified Infallibility and 2) the sacred traditions faithfully transmitted from generation to generation throughout the life of the Church by means of the proper use of the Apostolic Rule of Faith. Sacred tradition is therefore the very life of the Holy Trinity as Christ Himself has revealed it in and through the Church, as testified to by the Holy Spirit.
