“God is the Saviour of all men, especially those who believe.” (1Timothy 4:10)
The “summary” verses such the one quoted above proves that “God Saves All Men”. (note that “all men” (Full set of men) and “believers” (a subset of men) are distinctly distinguished in this one verse).
Note that it does not read: “God is the Saviour of believers from all men.” (for example)
By exact use of the word “specially” (Malista in Greek) and the exact grammar syntax consider:
“For there are many rebellious people, full of meaningless talk and deception, especially those of the circumcision group.” (Titus 1:10)
If the first verse (as wrongly) described by our ECT brethren claim it means “only believers are saved” (in 1 Timothy 4:10), then in the second verse (in Titus 1:10 shown here), we must have too by the same “logic” that there are “only” such (rebellious, deceivers) from the “circumcision group” (if following the “bringing into” logic).
The absurdity is obvious (literally).
