Anchs,
From the fact of the expanding, growing church - which is God's family.
From the fact of the underground Church in China, the persecurted Church in various nations, growing, fulfilling Scripture - and not a shower of hidebound traditionaluists.
"The Light shines in the darkness, and the darkness cannot extinguish it" (John 1:12, NLT)
Been a while since we had someone try the survivor bias fallacy. Congrats!
"Survivorship bias, or survival bias, is the logical error of concentrating on the people or things that "survived" some process and inadvertently overlooking those that did not because of their lack of visibility. This can lead to false conclusions in several different ways. The survivors may be actual people, as in a medical study, or could be companies or research subjects or applicants for a job, or anything that must make it past some selection process to be considered further.
Survivorship bias can lead to overly optimistic beliefs because failures are ignored, such as when companies that no longer exist are excluded from analyses of financial performance.
It can also lead to the false belief that the successes in a group have some special property, rather than just coincidence (Correlation proves Causation). For example, if three of the five students with the best college grades went to the same high school, that can lead one to believe that the high school must offer an excellent education. This could be true, but the question cannot be answered without looking at the grades of all the other students from that high school, not just the ones who "survived" the top-five selection process."
