For no other foundation can a man lay than what is laid, which is Jesus Christ.
All Commentaries on 1 Corinthians 3:11 Go To 1 Corinthians 3
Ambrosiaster
AD 400
Nobody can lay another foundation, because even if some people are heretics, they do not teach except in the name of Christ. They cannot commend the inventions of their error in any other way. So through the dignity of his name they try to make contradictory and absurd ideas acceptable. Commentary on Paul’s Epistles.
