John Chrysostom

"How was it then reckoned? when he was in circumcision, or in uncircumcision?"

For since he that pronounced it blessed was David, who was himself also in a state of circumcision, and he was speaking to those in that state, see how eagerly Paul contends for applying what he said to the uncircumcised. For after joining the ascription of blessedness to righteousness, and showing that they are one and the same thing, he enquires how Abraham came to be righteous. For if the ascription of blessedness belong to the righteous, and Abraham was made righteous, let us see how he was made righteous, as uncircumcised or circumcised? Uncircumcised, he says.
