During Mass, the priest says that we can share in the divinity of Christ - how is this possible?
Jesus does not have just a share in the divinity of the Father and the Holy Spirit; like them, He is fully divine and their equal. Yet He loves us so much, that He gives us some share in His divine life. He does this through the sacraments which give us sanctifying grace. Sanctifying grace raises us up to a super human level that we could never achieve on our own. This is a share in His divine life. But it is only a share. We don’t become His equal.
