Last I checked that Bible only references Christ as the only absolver of sins under the new covenant not man
Christ has always been the only absolver, even before the New Covenant. There is no other name under heaven by which we may be saved. Jesus gave this power to His Apostles, and they to their successors. Priests today absolve in the person of Christ.
"And behold, they brought to him a paralytic, lying on his bed; and when Jesus saw their faith he said to the paralytic, “Take heart, my son; your sins are forgiven.” 3 And behold, some of the scribes said to themselves, “This man is blaspheming.” 4 But Jesus, knowing[a] their thoughts, said, “Why do you think evil in your hearts? 5 For which is easier, to say, ‘Your sins are forgiven,’ or to say, ‘Rise and walk’? 6 But that you may know that the Son of man has authority on earth to forgive sins”—he then said to the paralytic—“Rise, take up your bed and go home.” 7 And he rose and went home. 8 When the crowds saw it, they were afraid,
and they glorified God, who had given such authority to men." Matt. 9
Notice the Apostle uses the plural “men” instead of one man. Jesus gave this authority to His Apostles.
Perhaps you might consider checking again?
and all examples of baptism in the Bible have been of adults who where immersed in water not children being sprinkled with water.
So how are these doctrines faithful to the Scripture?
That seems like taking some pretty hung non-spiritual liberties to me.
And I’m looking for Scripture, not just what you’ve be taught since you say the Catholic church is “scripturally faithful”.
Well, not all, but one must consider that the examples given are of adults because it was the beginning of the Church, and the adults converted first, then brought their children.
37 Now when they heard this they were cut to the heart, and said to Peter and the rest of the apostles, “Brethren, what shall we do?” 38 And Peter said to them, “Repent, and be baptized every one of you in the name of Jesus Christ for the forgiveness of your sins; and you shall receive the gift of the Holy Spirit. 39 For the promise is to you and to your children and to all that are far off, every one whom the Lord our God calls to him.” 40 And he testified with many other words and exhorted them, saying, “Save yourselves from this crooked generation.” 41 So those who received his word were baptized, and there were added that day about three thousand souls. Acts 2
Why would you assume that children are excluded? Infants have always been baptized until relatively recently. Modern Protestants who have rejected the Apostolic Teachings changed this to suit themselves.
