That is a serious twisting of what scripture says. Jesus said,
“IF YOU ABIDE IN MY WORD, you shall know the truth - and the truth shall set you free.”
Notice the huge “IF” at the beginning. Only those who “abide in His word” will know the truth - and only THEY will be set free.
Take out the first two phrases of this conditional statement, and you make a lie.....”the truth shall set you free.” which is NOT true if a.) you don’t abide in His word, and b.) then you will not KNOW the truth, and c.) the truth will be the truth - but it won’t set you free.
But any of us can so easily slide into subjectivism and relativism without realizing it, and believe that we abide in His word! That is why Jesus Christ founded a Church, made up of sinners, but with the promise to guide it until the end of time, in matters of faith and morals. A couple of examples of this would be the Eucharist and contraception.
When Pope Paul VI issued his prophetic encyclical, “HUMANAE VITAE” (1968), there was an incredible negative reaction not only on the part of the laity who wanted to enjoy the pleasures of sexual relationships without any responsibility or openness to life by using artificial birth control, but even on the part of a great number of priests and bishops, even entire Episcopal conferences (e.g., the ‘Winnipeg Statement’ of the Canadian Bishops)! BEFORE 1930 ALL MAINLINE PROTESTANT DENOMINATIONS WERE IN ACCORD WITH THE CATHOLIC CHURCH that the use of artificial birth control was a grave evil and a serious sin. When the Anglican Church changed its stance in 1930 (Lambeth Conference) the other protestants churches quickly followed suit while Pope Pius XI reaffirmed the Church’s constant teaching on this grave evil in his encyclical Casti Cannubii (1930). Do we believe that we can make it to heaven without imitating Christ crucified to overcome our egoism and to learn to truly love, without being generous to life (“be fruitful and multiply”; Gen 1:28; 9:1,7; 26:24; 38:8-10; Ps 8:6-9; 127:3-5; Sir 17:2-4; Ex 1:7; Wis 9:2; 10:2; etc.)? WE ARE NOW UNDERGOING THE CHASTISEMENT (Mt 24) of Divine Mercy, as the last chance of conversion (Diary of Saint Faustina, no. 1588), for our rejection and great rebellion against God’s holy and saving laws with “a personage not canonically elected, raised to the Pontificate, (who) will endeavor to administer shrewdly to many the mortal poison of his error!” (The “Prophecy” of Saint Francis (Assisi); http://spir-food.blogspot.it/2013/11/prophecy-st-francis.html).
Another example is the Eucharist. John chapter 6. It is interesting that the only verse in the whole Bible with the number 666 is John 6:66, when many disciples did not believe in the Eucharist!
The first target of Satan is the Catholic Church. You might find some of the references about this interesting in the article:
