The problem here is that our "moral tradition" we have come to know, was caused by the teaching of Scripture. If we only knew what the sexual morality was like before the Church age began? In lands outside of Israel? We would begin to see that our moral tradition is Scriptural, not having its origins in secularism.
Sidebar:
An interesting point that I have noticed over time, is that when RCC's wish to justify having their traditions? They resort to quoting Scripture to prove we are to have traditions.
Traditions are not simply something that began with human reasoning. Tradition is to be found in the foundation of Sola Scriptura.
Yet, tradition is not eternally binding. What may have been good tradition for one generation living in one kind of economy and culture, may not be a valid tradition for another time and place. Tradition can be flexible. Doctrinal truth must never be compromised.
The purpose for tradition is so that what is learned via Sola Scriptura can find an outlet of expression in protocol.
Tradition may have it, that there will be Church service held every other day of the week. Another church, it may be Sundays and Wednesdays. Tradition must be for the sake of Sola Scriptura. Not the other way around. Nor, should traition become the antichrist by replacing Scriptural directives with ones that contradict Scripture.
I do not think this should be an issue of Tradition versus Sola Scriptura. But, of good tradition versus bad tradition.
The Protestant church (all churches for that matter) have their own brand of traditions. The real issue is not if we should have tradition. But, rather. Is it good, or bad tradition? Does it compliment? Or, contradict? Scriptural truth!
The truth is that there are good traditions, and bad.
Tradition in itself is not a bad thing.
1 Corinthians 16:1-2 (New International Version)
"Now about the collection for God's people: Do what I told the Galatian churches to do. On the first day of every week, each one of you should set aside a sum of money in keeping with his income, saving it up, so that when I come no collections will have to be made."
Now that was a tradition established by Paul for his church in Corinth. Today? We might mail mail in a check, or have a box in the back of the Church..or pass a plate.
Yet, Scripture states we are to have a collection for those in Spiritual leadership. Traditions created by different churches will determine individually how each is to accomplish this.
How are we to know we are to have traditions? Sola Scriptura! That's how! (how ironic)
