Westminster Confession of Faith, Chapter XXVII, para. 4:There are only two sacraments ordained by Christ our Lord in the Gospel; that is to say, Baptism, and the Supper of the Lord: neither of which may be dispensed by any, but by a minister of the Word lawfully ordained. (Matt. 28:19; 1 Cor. 11:20, 23; 1 Cor. 4:1; Heb. 5:4)
2nd London Baptist Confession of Faith, Ch 28 (Of Baptism and the Lord's Supper):1. Baptism and the Lord's Supper are ordinances of positive and sovereign institution, appointed by the Lord Jesus, the only lawgiver, to be continued in his church to the end of the world.(Matthew 28:19, 20; 1 Corinthians 11:26)
2. These holy appointments are to be administered by those only who are qualified and thereunto called, according to the commission of Christ.(Matthew 28:19; 1 Corinthians 4:1)
The Belgic Confession, Article 33:We believe that our good God, mindful of our crudeness and weakness, has ordained sacraments for us to seal his promises in us, to pledge his good will and grace toward us, and also to nourish and sustain our faith.
He has added these to the Word of the gospel to represent better to our external senses both what he enables us to understand by his Word and what he does inwardly in our hearts, confirming in us the salvation he imparts to us.
For they are visible signs and seals of something internal and invisible, by means of which God works in us through the power of the Holy Spirit. So they are not empty and hollow signs to fool and deceive us, for their truth is Jesus Christ, without whom they would be nothing.
Moreover, we are satisfied with the number of sacraments that Christ our Master has ordained for us. There are only two: the sacrament of baptism and the Holy Supper of Jesus Christ.
Further, we believe that there is no mediator between God and man but the Man Jesus Christ, and that we have personal access through the authority of Christ to confess our sins to God. Beyond that, there is still the disagreement over the need for penance between the Protestants and the RCC. I'm sure that FR Religion forum is ripe with these debates (if you care to explore).
So do we. The sacrament of confession doesn't replace going to God and telling him you're sorry, in fact, if you haven't done it already, it's right there in the middle of the sacrament.
The issue is, what else did Jesus provide for us?
It's interesting to me that evangelicals now talk about having "accountability partners". They've come full circle -- an "accountability partner" is a big part of what a confessor does.
