The opening of the Holy Door which opens the special Jubilee. The chart is cast for Rome, December 8th 2015 11:11 am
Saturn, the ruler of the Ascendant is at MC together with the Sun and grants success to the event.
Furthermore notice that Saturn is an obvious choice because the jubilee is an year of forgiveness of sins and mercy: in the Old Testament is the latest of 49 years, seven times seven years.
Jupiter, the significator for the Pope is in his detriment, but strong by accidental dignity in the angular seventh house.
Moon and Venus, in the day dedicated to the Virgo and Her immaculate conception (She is free from sins before birth), are in the ninth house, the House of the God and Religion and Cults.
The Moon – by mundane position – is together with the star of Arcturus, the Guardian of the Northern Hemisphere, one of the brightest stars in the sky, of Mars & Jupiter nature, which bestows dignities and preferrement.
