Trying to help the misguided one person at a time. These two premises you made are wrong but they are constantly thrown out there like the annual egging of the neighbor's house on Halloween.
“You shall not make for yourself a graven image, or any likeness of anything that is in heaven above, or that is in the earth beneath, or that is in the water under the earth” (Exodus 20:4)—in order to keep the Catholic faithful in darkness as to the truth that they should not have statues in their churches.
Despite appearances, we know Exodus 20 is not a prohibition against making “any likeness of anything” in a strict sense because we clearly see God either commanding or praising the making of images and statues in multiple biblical texts (see Exodus 25:18; Numbers 21:8-9; I Kings 6:23-28, 9:3). Just five chapters after this so-called prohibition against statues, for example, God commands Moses to make statues representing two angels to be placed over the mercy seat of the Ark of the Covenant:
And you shall make two cherubim of gold… The cherubim shall spread out their wings above, overshadowing the mercy seat with their wings, their faces one to another…. And you shall put the mercy seat on the top of the ark… There I will meet with you (Ex. 25:18-22). There are five key points to be made concerning this common misunderstanding among Protestants as well as many quasi-Christian sects. https://www.catholic.com/magazine/online-edition/did-the-catholic-church-change-the-ten-commandments
“Catechism” comes from a Greek word, Katecheo, which simply means “to teach.”
"Lutherans, Anglicans, Presbyterians, and many other groups use a catechism. Martin Luther developed the Small Catechism, still used by Lutherans today, after going on a tour of the parishes under his care, and realizing how desperately they needed easy-to-understand instruction on Biblical truth. Catechism emphasizes the systematic teaching of Bible truth, based on foundational information that every believer should know. It’s a covering of the bases before moving on to other material. Many churches teach the catechism before baptizing or confirming church members."
Who can really read the bible that was transcribed and translated many times over the years without the help and instruction from great scholars. Take a quote from just the New Testament, "It is easier for a camel to pass through the eye of the needle, than for a rich man to enter into the kingdom of God." How can a camel ever pass through the eye of a needle? Without an understanding of language and mindset of humans 2,000 years ago we would never understand that on it face. I suppose a free-formed Holy Hopper Pastor from some obscure Evangelical assembly might get something right now and then.
