Strong's concordance is for use with the Scriptures. You used the term "anti-Christ" as follows:
That list is a list of ANTI-POPES! So the word anti can clearly mean a substitute for something.
A substitute for something in Scripture, yes. I believe you are taking the word anti as used in Strongs and assigning it a meaning outside of Scripture for use with "anti-popes".
Another point - do you maintain the ONLY meanings for "anti-" are contained in Strongs definition?
