When I was tonsured/ordained, Just before the liturgy began, Metropolitan Nicholas had me approach him at the altar, where he gave me the blessing to wear the cassock then had me sit in the congregation (1st pew) at the time of tonsuring I was lead up by the proto-deacon, and following the cutting of hair with the exclamation of Axios I was vested in the sticharion and following the reading the section of scripture went and joined serving the liturgy. I have heard of the short version of the phlenion being used, but it was not with me and I have never actually seen it.
