Thesis LVII. Yet however much both groups of Reformed teachers stress the efficacy of God's grace, they deny that it in any way harms the freedom of the human will. Whatever good works a person does by God's grace, he does freely.
So the very first act of conversion is just as free as the acts that follow it: it is not merely a living operation of our will but one the will freely brings forth.
Latin
LVII. Quantumcunque vero tum hi tum illi Scholae Reformatae Doctores efficaciam gratiae divinae exaggerent, nolunt tamen illam quicquam humanae voluntatis libertati praejudicare, sed quaecunque bona opera per Dei gratiam ab homine fiunt, ab iis libere fieri, adeoque primum ipsum actum conversionis non minus liberum esse, quam qui eum sequuntur, nec solum esse vitalem voluntatis nostrae operationem, sed ab ea libere elici.
