Is it true that Sola Scriptura or Bible alone believing Christians reject tradition and only think that the Bible holds infallible teachings?
All churches hold to traditions, and those who say they don’t aren’t being honest. Having Holy Communion weekly, monthly or quarterly is a tradition, for example.
Sola Scriptura essentially is the idea that the church should not claim any tradition, practice or doctrine to be infallible or necessary to salvation unless these can be proven by Scripture. Scripture alone is the infallible authority.
The 39 Articles of Religion puts it this way:
“Holy Scripture containeth all things necessary to salvation: so that whatsoever is not read therein, nor may be proved thereby, is not to be required of any man, that it should be believed as an article of the Faith, or be thought requisite or necessary to salvation.”
The Westminster Confession puts it this way:
“VI. The whole counsel of God concerning all things necessary for his own glory, man’s salvation, faith and life, is either expressly set down in Scripture, or by good and necessary consequence may be deduced from Scripture: unto which nothing at any time is to be added, whether by new revelations of the Spirit, or traditions of men.
[12] Nevertheless, we acknowledge the inward illumination of the Spirit of God to be necessary for the saving understanding of such things as are revealed in the Word:
[13] and that there are some circumstances concerning the worship of God, and government of the Church, common to human actions and societies, which are to be ordered by the light of nature, and Christian prudence, according to the general rules of the Word, which are always to be observed.
[14]”
Now, different Protestant churches apply Sola Scriptura in different ways and to different degrees. Ash Wednesday is a good example of this.
Some Protestants would say Ash Wednesday is not in the Bible, and therefore it is forbidden. Others would say that Ash Wednesday is not a necessary tradition, but it can be a beneficial observance as long as no one is made to feel like they have to take part.
