What is the purpose of the Rosary?

The purpose of the Rosary is twofold and corresponds to Jesus's commandments to love: firstly, the commandment to love the Lord our God with all our heart, mind and strength leads us to want to pray in such a way that we worship and glorify him; secondly, the commandment to love our neighbour as ourselves leads us to seek prayer that brings spiritual and moral benefits to ourselves while at the same time is an act of intercession for others. The Rosary is all of these things, thanks be to God.
