The Second Coming of the Lord Jesus?

MATTHEW 24:34 Verily I say unto you, This generation shall not pass, till all these things be fulfilled. MARK 13:30 Verily I say unto you, that this generation shall not pass, till all these things be done. LUKE 21:32 Verily I say unto you, This generation shall not pass away, till all be fulfilled. 1THESSA 4:16 For the Lord himself shall descend from heaven with a shout, with the voice of the archangel, and with the triumph of God: and the dead in Christ shall rise first. Now could any of you college-educated Catholic bible scholars tell me which of these inspired authors of God is revealing the truth as to when exactly Jesus is coming? After more than 2,000 years of waiting - time has already elapsed! Poch Suzara
