Adoption to Sonship

In the baptismal prayer in which the priest blesses the baptismal water, there is a line that baptism will bestow upon the candidate the loosing of bonds, the remission of sins, the illumination of the soul and “the gift of adoption to sonship”. The phrase “adoption of sonship” is a reference to the words of St. Paul, who used the word to describe our salvation in Christ in Ephesians 1:5. There he sums up our salvation by saying that God “predestined us to adoption to sonship [Greek υίοθεσία/ uiothesia] through Jesus Christ to Himself”. Given that this adoption to sonship serves to encapsulate and summarize our entire salvation, we must pay it closer attention and to what it all means.
