Indeed, but this is an inaccurate and misleading translation.
Holy Tradition is expressly sanctioned not just in 2 Thessalonians 2:15 but in 1 Corinthians 11:2 and by implication in Galatians 1:8-9
Thus in my view while Sola Scriptura as used by Luther, the Anglicans and John Wesley, all of whom valued tradition, is coherent, there are serious problems with the Nuda Scriptura model we see espoused by some Restorationist churches such as one of the larger Sabbatarian denominations, and by some Fundamentalists and other very heavily low-church groups, such as non-denominaitonal churches and megachurches, in that the total rejection of tradition is contradicted by the scriptural text itself.
