St. Brigid may be remembered as turning water into beer or the legend that she midwifed Mary in the birth of Jesus, but for those of us hoping for women’s advancement in the church, she preached to her flock, and founded a monastery for men and women, and became abbess there. Several of her images are shown with her holding a Bishop’s crosier. While there is some dispute if she was an actual bishop, she was the leader of both monasteries and the Abbess of Kildare is considered as the superior general of the monasteries in Ireland. Regardless of her official capacity as a pastor, Brigid’s oratory at Kildare became a centre of religion and learning, and developed into a cathedral city. 
Personally, I’m disappointed that when I visited Ireland a few years ago that I was so close to Downpatrick and didn’t visit. Her relics aren’t there any longer (not since 1538) but I still would have liked to have visited especially since the relics of Patrick, Brigid, and Columba (Columcille) had been there and all are said to have been buried there.
Imbolc dates back to ancient times and Celtic tradition has it beginning the night of February 1st and continuing through February 2nd. This speaks volumes, to me at least that this tradition was adopted/co-opted by the early Christians in the Celtic world. February 2nd is Candlemas, which commemorates the presentation of Jesus in the church. Imbolc is about halfway between the winter solstice and the spring equinox and foretells the coming of spring. Groundhog’s Day is February 2nd and he also foretells the coming of spring, whether after six more weeks of winter or right around the corner.
Beginning next year, St. Brigid’s Day will also be a public holiday in the Republic of Ireland.
So many things in our myths, traditions, and religions are interconnected; not all of them by chance or coincidence. Some were intentionally brought forward by the church to include the “pagans” in their conversion to Christianity. This feels almost like a “gentle Crusade” rather than at the point of a sword when they encouraged Jews and Muslims.
I’ve just completed reading a Celtic spirituality book that has nine chapters describing different Celtic ways along with the intertwining of Christianity. The second chapter was focused on St. Brigid and what she brought to Celtic spirituality in this author’s opinion: the Sacred Feminine. Celts had a tremendous respect for the feminine and how it balanced the world they lived, and we live in.
The book is an easy read. I chose to read one chapter a day. That let the information gradually process. There is also prayer and an appendix that would lend itself to daily prayer and meditation in the Celtic tradition.
