If it is just in Latin, its a lead that it was added by the Roman Church.
But still, I would like to look it up. Do you have any source I can check? I mean which work of Cyprian, which chapter, verse.

It comes from "On the Unity of the Church"

THE UNITY OF THE CHURCH 101
1 He who breaks the peace and concord of Christ acts against Christ; he who gathers somewhere out- side the Church scatters the Church of Christ.
The Lord says: 'I and the Father are one.'
2 And again of the Father and Son and the Holy Spirit it is written: 'And these three are one.'
3 Does anyone believe that this unity which comes from divine strength, which is closely connected with the divine sacraments, can be broken asunder in the Church and be separated by the divisions of colliding wills? He who does not hold this unity, does rot hold the law of God, does not hold the faith of the Father and the Son, does not hold life and salvation.
