"Terror"

From Eusebius, Oration of Constantine 12:

[D]octrine was entrusted to wise people. The truths they communicated could then be kept carefully and with pure consciences by their households. Then true, steadfast obedience to God's commands could be established and produce boldness in the face of death. Such boldness comes from a pure faith and genuine holiness before God. Those who are armed like this can withstand the world's storms.... They boldly overcome the greatest terrors and are considered worthy of a crown of glory. People like this don't accept praise but know full well that God gave them the power to endure and to fulfill His commands zealously. Such people will always be remembered and will receive everlasting honor.*

(*--Hence the Orthodox prayer at death, "Memory eternal" -- referring to the memory of God.)
