7:30am is Rite I, which is "Episco-speak" for a celebration of the Holy Eucharist that uses language in older Prayer Books. If you like worship that has thee/thou/hast, etc., then you might like Rite I. Rite I is a smaller congregation (around 70 worshippers) and there is less music. The sermon is the same. This service lasts about 50 minutes.
9am is Rite II. As you might imagine, Rite II uses language that is common to everyday speech. At Rite II, we have a choral support from a soloist or instrumentalist (which means more music) and a larger worshipping congregation (around 185). This service lasts about an hour. You may see a lot of children at 9am and you won't smell incense (unless it's lingering from last week at 11am!)
11 am is Rite I or II. At this service, we have a full choir (which means more music), a larger worshipping congregation (around 185), and more ceremonial which will include incense (more smells and bells) and chanting. A beautiful service that incorporates all the senses, this service lasts about an hour.
A 30 minutes Eucharist is celebrated each Wednesday at noon in the Chapel. Prayers for healing are offered at this service.
On certain Holy and Feast Days throughout the year, celebrations of the Eucharist will be offered at the Annunciation Altar in the Church.
