In Catholic teaching, to what scripture (OT and NT) is each of the seven sacraments referenced?
The seven sacraments are:
- Confirmation (or Chrismation),
- the Eucharist,
- the Anointing of the Sick,
- Holy Orders and
Summarized from http://catholic-resources.org/ChurchDocs/Sacraments.htm as pointed out by Reluctant_Linux_User:
Baptism - Mathew 28:19 - "Go, therefore, and make disciples of all nations, baptizing them in the name of the Father, and of the Son, and of the holy Spirit"
Confirmation - Acts 8:17; 19:6 - "Then they laid hands on them and they received the holy Spirit."
Eucharist - Luke 22:14-20 - The Last Supper
Penance1 - James 5:16 - "Therefore, confess your sins to one another"
Anointing of the Sick - James 5:14 - "Is anyone among you sick? He should summon the presbyters of the church, and they should pray over him and anoint [him] with oil in the name of the Lord"
Holy Orders - Acts 6:6 - "They presented these men to the apostles who prayed and laid hands on them."
Matrimony - Genesis 2:24 - "That is why a man leaves his father and mother and clings to his wife, and the two of them become one body."
I suggest reading the article linked about for more scriptural support and more information about how and why they are performed.
1. cf. Penny Catechism Q.283. When did our Lord institute the Sacrament of Penance? A. Our Lord instituted the Sacrament of Penance when he breathed on his Apostles and gave them power to forgive sins, saying: 'Whose sins you shall forgive, they are forgiven.' John 20:23
