No, the Catholic religion is not a false religion.
Here are some verses about Confession, Saints, and calling priests Father.
Sacrament of Confession/Reconciliation
Catholic Note:
Protestants have a hard time thinking that a man can give absolution for another's sins. They claim there is only one mediator between God and man: Jesus (1 Timothy 2:5). Catholics believe Christ gave His apostles the power to forgive sins, a power that has been handed down for generations through apostolic succession. The sacrament of reconciliation is Christ's gift to us. The root of all sin is pride; its antidote is humility. Confessing one's sins to God's appointed representative is thoroughly biblical, and calls for tremendous humility. The priest does not act on his own, He acts in the name of God and on behalf of His Church, administering God's forgiveness (absolution). The sacrament of Confession wipes away our sins, increases sanctifying grace in our souls, and reunites us with Christ and His Church. The Church is the extension of Christ's incarnation, and that extension takes place through the sacraments" (Scott Hahn , Swear to God, Page 22)
Jesus continues his example of priestly forgiveness in the Old Testament.
Leviticus 4:13-21 - "priests shall make atonement for them, and they will be forgiven"
Leviticus 5:14-26 - (Sin offering brought to the Old Testament priests, who make atonement for sinners' forgiveness.)
See also: - Leviticus 4:27-25, Leviticus 5:5, Numbers 5:8
Confession is not a private affair in the Bible.
Leviticus 5:14-26 - (Public confession with animal sacrifice)
Numbers 5:6-7 - "man ... commits a fault ... he shall confess the wrong he has done"
Matthew 3:6 - "baptized by him ... as they acknowledged their sins"
Acts 19:18 - "believers came forward and openly acknowledged their former practices"
James 5:16 - "confess your sin to one another ... that you may be healed."
See also: - Leviticus 26:39-42, Psalms 32:3-5, Proverbs 28:13, Mark 1:5
Jesus has power to forgive sins.

After forgiveness, the need for reparation can remain.

Veneration of the Saints
Joshua 5:14 - Joshua fell prostrate in worship before the angel
Daniel 8:17 - Daniel fell prostrate in terror before Gabriel
Tobit 12:16 - Tobiah and Tobit fall to the ground before Raphael
Matthew 18:10 - the angels in heaven are always before the face of God
Note: We venerate angels because of their great dignity, which comes from their union with God. Saints are also in united with God. Veneration nor honor IS NOT WORSHIP. Catholics worship GOD/Jesus alone!
Hebrews 13:7 - Remember your leaders, who preached the word of God to you, and as you reflect on the outcome of their lives, take their faith as your model
1 Thessalonians 1:5-8 - you become an example to all believers
Note: this is what Saints are for Catholics and all mankind: examples of holiness
1 John 3:2 - we shall be like him, for we shall see him as he is
Statues
Exodus 20:4-5 - do not make and worship any graven images
Commentary on Exodus 20:4
Only images of strange gods were prohibited as appears not only from the words in Exodus 20:5 and Deuteronomy 5:7 but also from the cherubim (Exodus 25:18) and the brazen serpent (Numbers 21:8) which Yahweh ordered to be made and from the mural decorations of the Jewish synagogues in the early Christian period as excavations abundantly attest. There is question therefore not of a separate commandment which forbids the worship of all images but of an application of the precept forbidding the worship of strange gods. The prohibition of image worship, already discussed, does not contemplate the case of an image of Yahweh, most probably forbidden in the Book of the Covenant. Deuteronomy 4:16 insists, however that he did not appear in material form lest the people should be led to make an image out of him and misapprehend his spiritual nature. The prohibition of idols is found in the Book of the Covenant. It appears here in an amplified form most probably as a later addition to the decalogue to illustrate and safeguard the first commandment. The Latin division of the commandments is thus the more reasonable one and the more likely to be original.
Exodus 25:18-19 - make two cherubim of beaten gold
Numbers 21:8-9 - Moses made bronze serpent and put on a pole
1 Kings 6:23-29 - temple had engraved cherubim, trees and flowers

2 Thessalonians 3:1 - finally, brothers, pray for us
Revelation 5:8 - angel offers prayers of the holy ones to God
Call No Man Father? (Matthew 23:9)
Catholic Note:
All human titles are only shadows of God's authority from which they derive, Ephesians 3:15. RE: "call no one on earth Abi father". "Father" is a term sometimes used of the great Rabbis. Note our Lord is not a grammarian regulating the use of terms: he is a doctor of the spirit. He forbids any acknowledgement of fatherhood that obscures the fatherhood of God, nothing more. If we make no allowance for the concreteness and brevity of his phrases we reduce either them to absurdity or him to inconsistency. He would not forbid a human son to use the word father nor would he forbid the term if addressed to one who is God's representative; in this second case, indeed, it serves to remind its user of the fatherhood of God. Nor must the Christian disciple pose as an independent spiritual guide. He himself is subject to one Teacher and one Guide - to the Lord Himself.
