I was trained to be an altar server prior to Vatican II and was required to memorize various Latin prayer responses at a very early age.

During the Offertory when the congregation responds to the priest's "Brethren, pray that my Sacrifice and yours may be acceptable to God the Father Almighty." with "May the Lord receive the Sacrifice from thy hands, to the praise and glory of His Name, to our benefit and that of all His holy Church."  I silently pray "Suscipiat Dominus sacrificium de manibus tuis ad laudem, et gloriam nominis sui, ad utilitatem quoque nostram, totiusque Ecclesiae suae sanctae.", drawn from the deep reaches of my childhood memories.  

I love the Mass in the vernacular because it allows the community to worship God as one.  However, I also cherish my little private "Latin moment" because it touches a spiritual chord deep within me that spans a lifetime.
