I’ll answer some of these as I take it you’re ignorant of the CC and just following what came up your way that testifies your disposition
Let just say you are not saying or doing anything new

My advice to you is to get this book, as it answers answered including the bigotry, If I had contact with you I’d gladly buy it for you

“Catholicism and Fundamentalism” The attack on Romansim” by “Bible Christians” by Karl Keating
I’ll see if I can lightly answer your query, not going to go into full details

What you need to know and understand is that not all generations were blessed with having a bible, the bible as we all have it today, that has only been around only in the last 100 years or so, as we didn’t have printing presses nor everyone was blessed with an education to read, most were ignorant, starting from the time of the apostles, furthermore traditions was the way to educate people in the past

The first, Christians experienced Christ Himself all the rest on man kind have not, so the church adopted what is known as the liturgical year to help the faithful meditate on and relive the key events of the life of Christ, such as His birth, ministry, passion, death, and resurrection. By following the liturgical calendar, believers can enter more deeply into the mysteries of the faith and journey through the salvific events of Christ's life each year, to experience Christ himself as the first Christians did, in other words Christ’s life is replayed to believers each and every generation,

His birth = Christmas, Lent as below, Easter his passion on the Cross and the resurrection, Pentecost is celebrated 50 days after Easter Sunday; and the Feast of Christ the King is celebrated on the last Sunday of Ordinary Time before Advent. and every day in between other points that can be found in the bible are only celebrated in a 4 year cycle, where the same event is celebrated but reading are taken from different gospels so the whole bible is covered, not only reading the bible but living it too

The observance of Lent is a traditional practice in the Catholic Church that prepares the faithful for the celebration of Easter. It involves prayer, fasting, and almsgiving as a way to reflect on Jesus' sacrifice and grow closer to God.

Matthew 4:1-2 - Then Jesus was led up by the Spirit into the wilderness to be tempted by the devil. And after fasting forty days and forty nights, he was hungry.

'The time of Lent is sacred to fasts and prayer, the time of abstinence, temperance, and self-denial.' As per imitation of Jesus, so one becomes more and more like Him

The Catechism of the Catholic Church teaches that Lent is a time of renewal, prayer, penance, and conversion. It prepares us to celebrate the Paschal mystery of Christ.
-------------------
The veneration of the saints in the Catholic Church is based on the belief that the saints, being perfected in God's grace, can intercede for us before God. This veneration is an expression of the communion of saints, where the Church on earth is united with the saints in heaven. The Bible verse that supports this practice is James 5:16, 'The fervent prayer of a righteous person is very powerful.' This verse shows the efficacy of the prayers of the righteous, such as the saints in heaven.

Penal substitution is the atonement in Christian theology that teaches that Jesus Christ, through His sacrificial death on the cross, took the punishment that humanity deserves for sin. This view emphasizes the idea that God's justice requires payment for sin, and Jesus willingly paid the penalty on behalf of humanity, thereby satisfying God's justice. This highlights the legal aspect of salvation, viewing it as a transaction where Christ's righteousness is imputed to believers, and their sins are imputed to Him.

Isaiah 53:5 which states, 'But he was wounded for our transgressions, crushed for our iniquities; upon him was the punishment that made us whole, and by his bruises we are healed.
2 Corinthians 5:21, 'For our sake he made him to be sin who knew no sin, so that in him we might become the righteousness of God.

And
The Bible does not provide explicit details on a specific mode of baptism, such as whether it should be done by immersion, pouring, or sprinkling. However, there are passages that describe the practice and significance of baptism. it does not mandate a specific technique for baptism.
