Pasach - or Passover - coincides with Good Friday.
Pentecost - In Christianity we use the same name - coincides with Christ going into Heaven.
Sukkoth - Feast of huts, or tents - the harvest - coincides with Christ's second coming.
Fr. Halbing then points out - these refer to "Christ has died, Christ has risen, Christ will come again." Something which is proclaimed in the Ordinary Rite just after the Mystery of Faith which is the Consecration of the Eucharist. It is good to remind everyone, the Mystery of Faith is NOT "Christ has died, Christ has risen, Christ will come again," for those are two statements of history and one of prophecy and there is no real mystery here. The Mystery of Faith, in the context of the Mass, is the Consecration of the Eucharist where mere bread and wine are substantially transformed into the Body, Blood, Soul and Divinity of Christ - THAT is the Mystery of Faith! But, to reiterate Fr. Halbing's point - that which is professed during the Ordinary Rite of the Mass comes to us from our Jewish heritage.
I have not finished this online Bible study yet myself, but thus far I am finding it quite interesting. If you are interested, I am including the video (and a link) below.
Fr. Halbing also does live Zoom meetings on Sundays, Mondays, Tuesdays and Wednesdays. You can find more information here: http://www.godswordalivetoday.org/
