Archaic KJV Word
Glorify
Modern equivalent: praise highly
What Was Lost
The making-visible. Jesus glorified the Father by making the Father's character visible through His actions. 'Glorify thy Son' was 'reveal who I truly am.' Glorification was not flattery but unveiling -- removing the covering so the real weight, magnificence, and character could be seen. To glorify God was to live so that His true nature became visible through you.
Closest Survivor in Modern English
glorify (still used in worship but heard as 'say nice things about God' rather than 'reveal God's true nature')
Peak Usage (1611)
KJV John 17:1 -- 'Father, the hour is come; glorify thy Son, that thy Son also may glorify thee'
Died still used but emptied (~1900)
Greek doxazo ('to reveal the true weight and character of/make the hidden nature visible/cause the real glory to shine forth') emptied into 'praise highly' or 'make look good.' The revelation dimension was replaced by flattery.
