Ephesians 2:8-9

“For by grace you are saved through faith,

and that not of yourselves,

for it is the gift of God;

Not of works, that no man may glory.”

“Douay-Rheims 1899 American Edition (DRA)”

Except that the "that" (the singular neuter demonstrative pronoun) is not referring to faith (a feminine noun); rather it and the subsequent "gift" (a singular neuter noun) are referring back to "the overwhelming wealth" (a singular neuter noun) in the previous verse 7. It's the "overwhelming riches of God's grace" that is the gift that we receive through faith.

[touto] (that) is neuter singular. [ploutos] (wealth) is masculine singular. It is unlikely that [ploutos] is the antecedent for [touto], otherwise we have an agreement error.

[touto] can reference a verb phrase: "[by grace] are ye saved". We know from many other contexts that "salvation" is the "election of grace" (Romans 11:5-7)
