If you know Jesus there is no need of mass, or confession in the Roman Catholic Church teaches. Romans 10.9,10 "That if thou shalt confess with thy my the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shat be saved. For with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation."
The conformation of this is by fellowship with Jesus anytime anywhere by the Holy Spirit who abides with us immediatehly upon confession Ephesians 1.13,14 "In whom ye also trusted, after that ye heard the word of truth, the gospel of your salvation: in whom also after that ye believed, ye were sealed with that holy Sprit of promise, which is the earnest of our inhertitance until the redemptiin of the purchased possession, unto the praise of his glory."
Know Jesus, no mass or confession needed.
