In response to the above quote:
I am a Lay Dominican. I’m not sure how it’s done in the other Orders, but we (the Dominican Laity) do NOT make vows–we make “promises”.
Our “Formation” is about 5 years, if I’m doing the math right–1st year is Inquiry, 2nd year, Candidate, 3rd-5th you’re Temporary Professed and then you make Lifetime Professed if you discern that you’re called to be a Lay Dominican. It is “patterned” after religious formation.
We DON’T wear habits or have religious names, although we do wear a Dominican cross and those of us who are Temporary Professed/Lifetime Professed can add “OPL” to the end of our name.
The Dominican Order considers us as part of the Dominican Family, right alongside with the Priests/Friars, Brothers, Sisters. Many of us are married, have families, jobs, and so on, and try to live according to St. Dominic/Dominican spirituality in our day-to-day lives.
Hope that helps!
