Im not sure where to look in terms of Catholic Apologetics, but I did see this on the CoC www….
The “faith page” lists all these different “Historic Testimonies” which they supposedly accept.
Here is the link to the Heidelburg Catechism on Infant Baptism and quote:
Should infants, too, be baptized?
Infants as well as adults
are in God’s covenant and are his people.
They, no less than adults, are promised
the forgiveness of sin through Christ’s blood
and the Holy Spirit who produces faith. Therefore, by baptism, the mark of the covenant,
infants should be received into the Christian church
and should be distinguished from the children
This was done in the Old Testament by circumcision,
which was replaced in the New Testament by baptism.
Also at here :
- Why should little children be baptized?
Little children should be baptized because the new life is a gift of God’s love, which little children need as much and are as able to receive as adults, for the Lord Jesus has promised unto them his Kingdom.
And the Presbyterian 1998 Cat:
Question 73. Are infants also to be baptized? Yes. Along with their believing parents, they are included in the great hope of the gospel and belong to the people of God. Forgiveness and faith are both promised to them as gifts through Christ’s covenant with his people. These children are therefore to be received into the community by baptism, nurtured in the Word of God, and confirmed at an appropriate time by their own profession of faith.
Concerning Confession I found Luthers Catechism on the UCC page and here is what it says:
CONFESSION AND ABSOLUTION
What is confession?
Confession consists of two parts. One is that we confess our sins. The other is that we receive absolution or forgiveness from the confessor as from God himself, by no means doubting but firmly believing that our sins are thereby forgiven before God in heaven.
What sins should we confess? Before God we should acknowledge that we are guilty of all manner of sins, even those of which we are not aware, as we do in the Lord’s Prayer. Before the confessor, however, we should confess only those sins of which we have knowledge and which trouble us.
About Original Sin, I think that one would be hard to find, here is what the Hedelburg Catechsim says, but I dont think its the same.
Here is what their own faith page says, do they still deny it?
