That reminds me of the old prosecutorial question, “Are you still abusing your wife?”
As
this link demonstrates, they are now regularized. You might also be able to see an advertisement for St. Benedict Center on the webpage of the
diocesan newspaper (I’m not sure how frequently the ads are rotated.) Bishop McManus administered the Sacrament of Confirmation (according to the 1962 Pontificale) at the IHM Chapel last year.
There are three regularized groups in Still River: St. Benedict Center (Slaves of the Immaculate Heart of Mary or MICM), St. Benedict Abbey (Benedictines), and the Sisters of the Slaves of the Immaculate Heart of Mary (St. Ann’s Convent).
There is still a group in New Hampshire, calling itself the Slaves of the Immaculate Heart of Mary, under the name Saint Benedict Center, which is not regularized. Pray for them.
