The
seal is a symbol close to that of anointing. “The Father has set his
seal” on Christ and also seals us in him.⁵⁰ Because this seal indicates
the indelible effect of the anointing with the Holy Spirit in the sacraments of
Baptism, Confirmation, and Holy Orders, the image of the seal (sphragis) has
been used in some theological traditions to express the indelible
“character” imprinted by these three unrepeatable sacraments.
