The Pasch And Forgiveness

Vocationis autem hujus ad poenitentiam principale est beneficium, gratuita remissio peccatorum. Pro qua idem Redemptor noster, peracto paschalis coenae convivio, sanguinem summ enuntiat effundendum. Bibite, inquit, ex hoc omnes. Hic est enim sanguis meus novi Testamenti, qui pro multis effundetur in remissionem peccatorum. Hanc igitur, sicut arbitror, aut omnes, aut pene omnis qui quolibet modo appellatur Christiano nomine, invenire desiderat; sed interest ubi quisque, vel quando, val qualiter quaerat. Neque enim ad remissionem peccatorum poterit pervenire, si quis aut veram non teneat fidem, aut negligat bonae operationi concessum divinitus tempus mortifera praeoccupatus vanitate contemnat. Haec namque tria, id est, fides, opus et tempus, ita sunt simul hominibus in hac vita necessaria, ut si cui num ex his tribus in praesenti saeculo defuerit, aeternae vitae particeps esse non possit; ac per hoc nec remissionem peccatorum consequentur, per quam ad aeternae vitate praemium pervenitur. Sanctus Fulgentius Ruspensis, De Remissione Peccatorum, Lib I Caput V Source: Migne 65.531a-b

The call to penance is principally a benefit, the gratuitous remission of sins. For which our Redeemer, at the gathering of the Paschal Meal, proclaimed with the pouring out of His own blood. 'Drink from this all of you. For this is the blood of the New Testament, which is poured out for many for the forgiveness of sins.' 1 This, therefore, I judge, either all, or almost all, desire to find who are called by the name of Christian, but it matters where and when and in what way a man seeks. For he shall not be able to obtain forgiveness of sins, if he does not hold to the true faith, or if he scorns the Divine largess by neglect of good works, caught up in fatal vanities. For these three, that is, faith, work, and time, are all together necessary for men in this life, so that if he lacks one of these three in the present world, he is not be able to participate in the eternal life, unable to obtain the forgiveness of sins by which comes the reward of eternal life. Saint Fulgentius of Ruspe, On the Forgiveness of Sins, Book 1, Chap 5 1 Mt 26.28
