Pelagius — on Rom 15:5 (PELAGIUS'S COMMENTARY ON ROMANS)

“The God of steadfastness is the Holy Spirit, who grants that with one mind, in accordance with Christ, we may glorify the God and Father of our Lord Jesus Christ. His steadfastness is meant to lead to repentance, and his encouragement is for those who have already repented.We are to live in harmony, so that each one may seek the salvation of the other as if it were his own, just as Christ saved everyone from death by his own death.”
