Symbol of the Cross on Baptism Records

Hello Everyone, does someone know what a symbol of the cross on the margin next to Baptism record signifies. Also, there is a latin phrase on this record I could not translate "sus ceper unt eg a sacrofente" I dont see it on many other records.I tried Latin translate with no luck.
Its for an ancestor,
Regina Duran
Baptised 4-17-1658
Nochistlan,Zac.
Parents Andres Duran y Juana de la Ascension
Siblings Joseph Duran 1656, Marcos Duran 1669, Diego Duran 1672,Maria Duran 1778
Also, any info with Duran Grandparents from Nochistlan going further back would be appreciated.

Thanks
