What are the attributes of the `life' Jesus is referring to in Jn 5: 26 where he speaks of `life in himself' granted by the Father?

We read in Jn 5: 25-26 (NRSVCE): >Very truly, I tell you, the hour is coming, and is now here, when the dead will hear the voice of the Son of God, and those who hear will live. For just as the Father has life in himself, so he has granted the Son also to have life in himself. My question is: According to Catholic scholars, what are the attributes of the ‘life’ Jesus is referring to in Jn 5: 26 where he speaks of ‘life in himself’ granted by the Father ?
