“Catholics believe that the Sacraments are how we cross over 2,000 years and become ‘contemporary with Christ,’ or rather how Christ crosses over and becomes contemporary with us. The answer is that we meet not just spiritually and subjectively, in our minds; we meet materially and objectively in and through the matter of the Sacraments.”
Peter Kreeft, Jesus Schock
The sacraments are efficacious signs of grace, instituted by Christ and entrusted to the Church, by which divine life is dispensed to us” through the work of the Holy Spirit (CCC, nos. 1131; cf. no. 774)
