coming
Three words are used in connection with the return of the Lord:
(1) Greek, "Parousia", meaning "personal presence," also used by Paul of the "coming" of Stephanas (1 Corinthians 16:17) of Titus (2 Corinthians 7:6); (2 Corinthians 7:7) and of his own "coming" to Philippi (Philippians 1:26). The word means simply personal presence, and is used of the return of the Lord as that event relates to the blessing of the saints; (1 Corinthians 15:23); (1 Thessalonians 4:14); (1 Thessalonians 4:17) and to the destruction of the man of sin (2 Thessalonians 2:8).
(2) Greek, "Apokalupsis", meaning "unveiling," "revelation." The use of this word emphasizes the visibility of the Lord's return. It is used of the Lord (2 Thessalonians 1:7); (1 Peter 1:7); (1 Peter 1:13); (1 Peter 4:13) of the sons of God in connection with the Lord's return (Romans 8:19) and of the man of sin (2 Thessalonians 2:3); (2 Thessalonians 2:6); (2 Thessalonians 2:8) and always implies visibility.
(3) Greek, "Epiphaneia", meaning "appearing," translated, "brightness" (2 Thessalonians 2:8) A.V.; "manifestation," R.V.), and means simply an appearing. It is used of both advents. (2 Timothy 1:10); (2 Thessalonians 2:8); (1 Timothy 6:14); (2 Timothy 4:1); (2 Timothy 4:8); (Titus 2:13).
