What are the duties of Deaconesses and Cohospitae?
The Celtic Church has an emphasis on blessings. The right hand of every person Baptized in a Celtic church was anointed with Chrism in the form of a cross so that the person could bless themselves, food, family, home, tools or whatever they were about to use. Celtic Bishops bless anyone who takes on duties in the Church. Women are no exception. Among the titles mentioned by ancient Celtic Christian writers are Co[n]hosptiae and Deaconesses. They are not Sacramental/Eucharistic ministers but have other duties. Neither has a Sacramental function.

Conhospitae are assistants to the Clergy who do good works outside of the altar. Some are chanters or choir directors, some are church school teachers.

A Deaconess performs various functions. She chants, and assists with the Baptism of women. She is also in charge of parish catechesis and office administration. In event that the Pastor perceives the need to have another present during an interview or even a Confession, the Deaconess will observe the discussion at a distance and remains outside of the range of hearing.

In some places she reads the Apostle (Epistle) from the nave, not the front of the Altar.

She may not proclaim the Gospel, preach at Liturgy, or distribute Holy Communion. Her special role is of social ministry, particularly to women, widows, the elderly, the sick, and children.
