The what??? Doing what??? This concept of "church" being some organization brings some really weird comments.
It seems to me, in your own comments, that you have divorced the Church from Protestantism by writing "Most Protestant "churches" are simply daughters of the Catholic Church and retain many of her errors." So I think it is natural to ask the above question. Is the Church evolving and progressing ?
Your question indicates a total lack of understanding as to the meaning of the word ekklesia. It is therefore irrelevant to scripture and impossible to answer.
