However there's a difference between simplemindedness and simplicity. Simplemindedness is easy to articulate. Simplicity is often too simple for words, and thus hard to articulate.
You go your way. I'll go His.
In case you might have the notion that I "figured it all out" on my own:
John O'Brien, Ph.D., LL.D.: "But since Saturday, not Sunday, is specified in the Bible, isn't it curious that non-Catholics who profess to take their religion directly from the Bible, and not the Church, observe Sunday instead of Saturday? Yes of course, it is inconsistent; but this change was made about 15 centuries before Protestantism was born, and by that time the custom was universally observed. They have continued the custom, even though it rests upon the authority of the Catholic Church and not upon an explicit text in the Bible. That observance remains as a reminder of the Mother Church from which the non-Catholic sects broke away - like a boy running away from home but still carrying in his pocket a picture of his mother or a lock of her hair." Faith of Millions, pp. 543 and 544.
"The Sabbath was Saturday, not Sunday. The Church altered the observance of the Sabbath to the observance of Sunday. Protestants must be rather puzzled by the keeping of Sunday when God distinctly said, 'Keep holy the Sabbath Day.' The word Sunday does not come anywhere in the Bible, so, without knowing it they are obeying the authority of the Catholic Church." Canon Cafferata, The Catechism Explained, p. 89.
Strange as it may seem, a lot of my faith is based on the teachings of these Catholic authoritarians.
