Why the term "Prayer Warrior"?

[HCTC]

How did the use of the term “Prayer Warrior” come about? I just think it is odd to use the vocabulary of conflict to describe someone who offers up prayer for the intentions of others. Wouldn’t something like “Prayet Pilgrim” be more appropriate - as in the person who prays is a faithful devotee?

 

[Fr.Charles_Grondin]

Its an expression based on Scripture’s metaphor of faith and prayer as armor and shield against evil:

Put on the armor of God so that you may be able to stand firm against the tactics of the devil. For our struggle is not with flesh and blood but with the principalities, with the powers, with the world rulers of this present darkness, with the evil spirits in the heavens. Therefore, put on the armor of God, that you may be able to resist on the evil day and, having done everything, to hold your ground. So stand fast with your loins girded in truth, clothed with righteousness as a breastplate, and your feet shod in readiness for the gospel of peace. In all circumstances, hold faith as a shield, to quench all [the] flaming arrows of the evil one. And take the helmet of salvation and the sword of the Spirit, which is the word of God. With all prayer and supplication, pray at every opportunity in the Spirit.

• Ephesians 6:11-18

Your opponent the devil is prowling around like a roaring lion looking for [someone] to devour. Resist him, steadfast in faith, knowing that your fellow believers throughout the world undergo the same sufferings.

• 1 Peter 5:8-9

The LORD is my strength and my shield

• Psalm 28:7

The night is almost gone, and the day is near Therefore let us lay aside the deeds of darkness and put on the armor of light.

• Romans 13:12

But since we are of the day, let us be sober, having put on the breastplate of faith and love, and as a helmet, the hope of salvation.

• 1 Thessalonians 5:8
