The Didache (pronounced 'Didarkay') is a Christian manual giving unique details regarding baptism, eucharist and church leadership from an early period of Christian development. Its name comes from the title, 'The Teaching (Didache) of the Lord, by the Twelve Apostles, to the Gentiles'. A rough table of its contents runs as follows:

Didache 1-6 - a collection of Jewish moral instructions to be adopted by Gentiles who want to be baptised.

Didache 7 - brief instructions for the baptism service itself.

Didache 8 - instructions for fasting and prayer, including a version of the Lord's Prayer that is very similar, but not identical, to that in Matthew's Gospel.

Didache 9 and 10 - two sets of eucharistic prayers.

Didache 11-15 - various instructions regarding church leaders and visitors.

Didache 16 - a warning about the events of the last days.
