What is the purpose of life according to Catholic and Orthodox Churches?

### Question **What do the Catholic and Orthodox Churches say is the (or the main or highest) purpose of human life for the regenerate?** ### Background Recent efforts to discover what “Christianity” says is the purpose of life (for the saved if/when a distinction is required), led me to a variety of answers among Protestants, covered mostly by Which is the purpose of life: * Love the Lord your God with all your heart and with all your soul and with all your mind. Love your neighbor as yourself. * Glorify God and enjoy him forever. * Learn the will of the Lord and then do it. * Know and Love God. **What about the rest of Christendom?**
