Salvific is an adjective that means related to the power of salvation.
The Latin word salvus (SOL voos) means safe. Our word of the day emerged in the late 16th century, taking on a theological connotation, as in: ‘the salvific power of the Lord.’ Today the word is still used almost entirely in a religious context.
Ellen treated the concert tickets as if they were religious artifacts. The way she revered them, you’d think those tickets had salvific powers.
