I was a member of an American Baptist church that had Deaconesses. We prepared communion to be served once a month and kept track of those who were sick and the shut-ins. We took food to those recovering from hospitals stays, etc.
The church needs such service, and it doesn’t infringe on any Biblical restrictions with regard to women teaching men.
A deacon in the RC tradition can give communion. That is where the line is drawn in the sand...
The only ones pushing for 'Deaconesses' are those who want a toehold into Holy Orders.
