In the Orthodox church the sacraments are called mysteries.
This is just a very short explication to give you an introduction of them.
The 7 mysteries are:
- Baptism
- Chrismation
- Confession
- Eucharist
- Holy unction
- Ordination
- Marriage
In the Orthodox church the number of mysteries is larger but everyone agree on this one as a clear answer to the church of Rome.
