I was reading this entry in the Catholic Encyclopedia about the theological concept of Tradition (as a source of revealed truth different from the Scripture). The author states that the Protestant rejection of tradition lead to logical inconsistencies in their doctrine/practice (if I understood it correctly). I would like to know which are some replies from Protestant theology to these comments. I show below some key paragraphs:
Now in this respect there are several points of controversy between Catholics and every body of Protestants. Is all revealed truth consigned to Holy Scripture? or can it, must it, be admitted that Christ gave to His Apostles to be transmitted to His Church, that the Apostles received either from the very lips of Jesus or from inspiration or Revelation, Divine instructions which they transmitted to the Church and which were not committed to the inspired writings? ... The Protestant principle is: The Bible and nothing but the Bible; the Bible, according to them, is the sole theological source; there are no revealed truths save the truths contained in the Bible; according to them the Bible is the sole rule of faith: by it and by it alone should all dogmatic questions be solved; it is the only binding authority. Catholics, on the other hand, hold that there may be, that there is in fact, and that there must of necessity be certain revealed truths apart from those contained in the Bible; they hold furthermore that Jesus Christ has established in fact, and that to adapt the means to the end He should have established, a living organ as much to transmit Scripture and written Revelation as to place revealed truth within reach of everyone always and everywhere.
... it is impossible to be satisfied with the Bible alone for the solution of all dogmatic questions. ... Catholic controversialists soon proved to the Protestants that to be logical and consistent they must admit unwritten traditions as revealed. Otherwise by what right did they rest on Sunday and not on Saturday? How could they regard infant baptism as valid, or baptism by infusion? How could they permit the taking of an oath, since Christ had commanded that we swear not at all? ... Where is it indicated in the Bible that the Bible is the sole source of faith?
In a similar way [controversies] show that [Protestants] cannot dispense with a teaching authority, a Divinely authorized living magistracy for the solution of controversies arising among themselves and of which the Bible itself was often the occasion. Indeed experience proved that each man found in the Bible his own ideas ... One man found the Real Presence, another a purely symbolic presence, another some sort of efficacious presence. The exercise of free inquiry with regard to Biblical texts led to endless disputes, to doctrinal anarchy, and eventually to the denial of all dogma. These disputes, anarchy, and denial could not be according to the Divine intention. Hence the necessity of a competent authority to solve controversies and interpret the Bible. To say that the Bible was perfectly clear and sufficient to all was obviously a retort born of desperation, a defiance of experience and common sense. Catholics refuted it without difficulty, and their position was amply justified when the Protestants began compromising themselves with the civil power, rejecting the doctrinal authority of the ecclesiastical magisterium only to fall under that of princes.
I am sorry for the long quotes, but I think they provide the line of argument to be counterattacked.
It seems, according to this question, that Luther, Calvin, and Wesley were against the Magisterium (and thus against the Tradition?), by stating that the Scripture is the sole source of revealed truth.
So the question is, how do Protestant theologies defend the aforementioned attacks of logical inconsistency, namely that there is necessarily a dogmatic choice involved in their theology which cannot be supported by the Holy Scripture?
Notice that I am not particularly interested in defences of specific instances given in the text (e.g. rest on Sundays), but rather on the more general principle of how unwritten traditions adopted by Protestantism are not logically inconsistent with their Sola Scripture belief.
