@theefaith argues for the efficacy of grace, suggesting that grace is necessary for our works to "bear fruit".
He says for instance, "
United to Christ in faith and baptism we are called to employ the grace of God that makes us saints!"
He certainly doesn't need me to clarify his position, but I believe that when a Catholic speaks about "employing grace" he speaks of the sacraments, which are the means to Grace.
The term "saint" comes from the Latin word "sanctus", which means "holy". In the Catholic view, if I am not mistaken, the objectification or actualization of God's grace is holiness.
theefaith doesn't indicate the "fruit" produced by employing grace, but one of the scriptures he quoted stands out as the prime example:
"2 Corinthians 12:9
And he said unto me, My grace is sufficient for thee: for my strength is made perfect in weakness. Most gladly therefore will I rather glory in my infirmities, that the power of Christ may rest upon me."
"Fruit" is what the farmer expects from the plants he planted. If he plants an apple tree, for instance he expects it to produce apples. What "crop" was Paul expecting to produce? Converts to the Gospel of Christ. And Paul seems to deny that he is ulitmately responsible for the crop of new converts, relying on the power of Christ instead.
theefaith seems to imply that Paul was employing the grace of God, which is why his ministry was effective, i.e. produced fruit -- many converts. But I could be wrong about what theefaith meant to say.
