G0054–ἁγνότης–hagnotēs

in pureness, in knowledge, in long-suffering, in kindness, in the Holy Spirit, in love unfeigned,

ἁγνότητι, hagnotēti “purity,”

and I fear, lest, as the serpent did beguile Eve in his subtilty, so your minds may be corrupted from the simplicity that `is' in the Christ;

ἁγνότητος hagnotētos “purity”
