... the Apostle Peter declared that the Church was built by the Holy Spirit. For you read that he said: 'God, Who knows the hearts of men, bore witness, giving them the Holy Spirit, even as was given to us; and He made no distinction between us and them, purifying their hearts by faith' (Acts 15:8-9). In which is to be considered, that as Christ is the Cornerstone, Who joined together both peoples into one, so, too, the Holy Spirit made no distinction between the hearts of each people, but united them.

What will you do if your product still further increases next year? You should then destroy again the warehouses which you are now preparing to build, and build bigger. For the reason why God has given you fruitful harvests is that He might either overcome your avarice or condemn it; wherefore you can have no excuse.

For it was not to our advantage to know; in order that we being ignorant of the actual moments of judgment to come, might ever be as it were on guard, and set on the watch-tower of virtue, and so avoid the habits of sin; lest the day of the Lord should come upon us in the midst of our wickedness.

We do not innovate anything ... How is it that novelties are introduced which were never even thought of by our predecessors?
