About the seven-year penance for those who sacrifice more than once.
Those who for the 2nd and 3rd time under compulsion made a sacrifice, let them fall asleep for 4 years, remain in communion for 2 years without communion of the Holy Mysteries, and on the 7th they will be finally accepted.
Greek original
Οἱ δὲ δεύτερον καὶ τρίτον θύσαντες μετὰ βίας, τετρατίαν ὑποπεσέτωσαν, δύο δὲ ἔτη χωρὶς προσφορᾶς κοινωνησάτωσαν, καὶ τῷ ἑβδόμῳ τελείως δεχθήτωσαν.
