quoniam vir caput est mulieris, sicut Christus caput est Ecclesiæ: ipse, salvator corporis ejus.
Because the husband is the head of the wife, as Christ is the head of the church. He is the saviour of his body.
Quia viro capite es de muliere, sicut Christo capite es de Ecclesia: ipso, salvatore de corpore de illo.
