Twenty-four post-biblical teachings that shape modern Christianity — who invented them, when, and what Scripture actually says. For the institutional lineage that produced them, see the Christianity Tree.
← Back to the Christianity TreeYeshua to the Pharisees
"In vain do they worship me, teaching as doctrines the commandments of men." (Mark 7:7) Every doctrine on this page was added after AD 30. Each was taught by men, codified in councils, and enforced by institutions Yeshua never built. The Brit Chadashah is silent on every one of them. The test is not how many believe a doctrine. The test is whether it is written.
* Acts 17:11 — search the Scriptures whether these things be so.
Constantine's edict, then Council of Laodicea
The seventh-day Sabbath was replaced by Sunday rest as "the Lord's Day." Sabbath-keeping was outlawed as "Judaizing."
The seventh day is sanctified at creation (Genesis 2:2-3) and given as an eternal sign (Exodus 31:13-17). Yeshua kept Sabbath. The apostles kept Sabbath. No verse changes the day.
Replaces Saturnalia / Sol Invictus
December 25 marks Yeshua's birth, celebrated with gift exchange and a decorated tree.
The shepherds were in open fields (Luke 2:8) — not December in Judea. Jeremiah 10:2-4 warns directly against cutting a tree and decorating it. Yeshua never asked to be celebrated this way.
Council of Nicaea — severs from Pesach
A spring resurrection holiday with eggs and rabbits, named for Eostre / Ishtar, intentionally separated from the Jewish Passover.
"Messiah our Pesach is sacrificed for us" (1 Corinthians 5:7). Leviticus 23 sets the feast on the 14th of Aviv — not the Sunday after the spring equinox.
Augustine of Hippo
Every human inherits Adam's guilt at birth. Infants are damned without baptism.
"The soul who sins shall die. The son shall not bear the iniquity of the father." (Ezekiel 18:20) Sin is what each person commits, not what they inherit at birth.
Martin Luther
Salvation is by belief alone. Works contribute nothing. Obedience is optional fruit, never required evidence.
"Faith without works is dead." (James 2:17, 26) "Not by faith only." (James 2:24) Luther tried to remove James from his Bible. Yeshua taught: "If you love Me, keep My commandments." (John 14:15)
Modern Free Grace / popular Calvinism
A one-time profession of faith guarantees salvation regardless of how the life that follows is lived.
"It is impossible to renew them again to repentance" if they fall away (Hebrews 6:4-6). Those who escape and return are "worse off than at the beginning" (2 Peter 2:20-22). Endurance matters (Matthew 24:13).
John Nelson Darby
Believers will be secretly snatched away before a seven-year tribulation. Those left behind face the antichrist.
"Immediately AFTER the tribulation of those days... He shall send His angels and they shall gather together His elect." (Matthew 24:29-31) No church father taught a pre-trib rapture. Darby invented it in 1830.
Cyrus Scofield Reference Bible
God has two distinct peoples — Israel and the Church — with separate destinies and separate prophetic timelines.
"One olive tree." (Romans 11:17-24) Yeshua "made both one" (Ephesians 2:14-16). "There is neither Jew nor Greek... ye are all one in Messiah Yeshua." (Galatians 3:28-29)

Believers vanish, the world descends into chaos, the antichrist rises during a seven-year tribulation.
A novelization of Darby's invention. The biblical pattern is endurance THROUGH tribulation (Revelation 13:10, 14:12), not escape from it. The saints overcome — they do not vanish.
Fourth Lateran Council
At the priest's words, bread and wine literally become Yeshua's body and blood. The sacrifice is re-offered.
"Do this in remembrance of Me." (Luke 22:19) A memorial, not a re-sacrifice. Yeshua's offering was "once for all" (Hebrews 10:10). It does not need repeating.
Augustine systematized it
Babies must be baptized to wash away original sin. Without it, they are damned.
Every baptism in Scripture follows belief and repentance (Acts 2:38, Acts 8:36-37). Infants cannot believe, repent, or confess Yeshua. The doctrine depends on original sin — which is itself unscriptural.
Fourth Lateran Council mandated annual confession
Sins must be confessed to an ordained priest, who absolves on God's behalf.
"One mediator between God and man, the man Messiah Yeshua." (1 Timothy 2:5) "If we confess our sins, He is faithful and just to forgive us." (1 John 1:9) The priesthood of Yeshua needs no human intermediary.
Gregory the Great → Council of Florence
A middle realm where the saved are purified by suffering before they are admitted to heaven.
"It is appointed unto men once to die, but after this the judgment." (Hebrews 9:27) Not in any book of the Tanakh or Brit Chadashah. Built from 2 Maccabees and church tradition.
Augustine → Aquinas
The wicked suffer endless conscious torture in hellfire forever, without rest or end.
"The wicked... shall be ashes under the soles of your feet." (Malachi 4:1-3) "Fear Him who is able to DESTROY both soul and body in Gehenna." (Matthew 10:28) "The wages of sin is death." (Romans 6:23)
Medieval Rome · Trent reaffirmed
Time in purgatory can be reduced by money, masses, or pilgrimages. The Church holds a "treasury of merit."
"Your silver perish with you, because you have thought that the gift of God may be purchased with money." (Acts 8:20) The error that triggered Luther's 95 Theses — and that Rome never abandoned.
First Vatican Council
When the Pope speaks ex cathedra on faith or morals, he cannot err. His teaching is binding on all Christians.
"One mediator between God and man." (1 Timothy 2:5) "Though we, or an angel from heaven, preach any other gospel... let him be accursed." (Galatians 1:8) No man stands between you and the Father.
Second Council of Nicaea
Statues, paintings, and relics of saints may be venerated as the worshipper looks "through" the image.
"Thou shalt not make unto thee any graven image... thou shalt not bow down thyself to them, nor serve them." (Exodus 20:4-5) The second commandment is not optional.
Pope Pius IX
Mary was conceived without original sin. She was sinless from the womb and remained so her entire life.
"My spirit hath rejoiced in God my Savior." (Luke 1:47) Mary herself needed a Savior. "All have sinned and come short of the glory of God." (Romans 3:23) No exception is granted.
Justin Martyr · Augustine · mainstream until Nostra Aetate
The Church has replaced Israel in God's covenant. The Jewish people are cursed wanderers, their election transferred to gentile believers.
"Has God cast away His people? God forbid." (Romans 11:1-2) The olive tree of Israel still stands. Gentiles are grafted IN, not transplanting. The root supports the branches, not the other way around.
Marcion (2nd c.) → modern "we are not under Torah"
The Torah was nailed to the cross and abolished. Believers are free from its commands. Obedience to the commandments is "legalism."
"Do not think that I came to abolish the Torah." (Matthew 5:17-19) "Do we then make void Torah through faith? God forbid: we establish Torah." (Romans 3:31) Yeshua kept Torah and taught it.
Scofield → Hagee · mainstreamed post-1948
The modern political state of Israel is the prophetic vehicle for end-times events. Unconditional political support is a Christian obligation.
"They are not all Israel which are of Israel." (Romans 9:6) The covenant remnant is defined by faithfulness to Torah and Messiah, not by passport or geopolitics.
Kenyon → Hagin → Copeland → Osteen
God wants every believer wealthy, healthy, and successful. Faith activates a divine wealth-transfer mechanism. Poverty is unbelief.
"The Son of Man has nowhere to lay His head." (Matthew 8:20) "Those who desire to be rich fall into temptation and a snare." (1 Timothy 6:9-10) The apostles died poor, beaten, and imprisoned.
B.B. Warfield · modern Reformed
Spiritual gifts — prophecy, tongues, healing — ceased with the apostolic age. The Spirit no longer operates this way.
Gifts cease "when that which is perfect is come" (1 Corinthians 13:8-10) — at Yeshua's return, not at the close of the canon. "Your sons and daughters shall prophesy" in the last days (Joel 2:28).
C. Peter Wagner · Bill Johnson · Bethel
Modern "apostles" and "prophets" hold restored governmental offices over the church. The "Seven Mountain Mandate" calls for Christian dominion over politics, media, business, and culture.
Ephesians 4:11-12 lists gift functions — not governmental offices. The "Seven Mountain Mandate" is not in any book of Scripture. Yeshua's kingdom is not of this world (John 18:36).
Every doctrine on this page was added after AD 30. Most were added centuries later, by men with power to enforce their preferences. None of them appears in the words of Yeshua. None of them appears in the apostolic writings. Each one is held up as essential by an institution that did not exist when Yeshua walked the earth.
The Berean test stands: search the Scriptures whether these things be so. If a doctrine cannot survive Acts 17:11, it should not survive your shelf.
"Thus have ye made the commandment of God of none effect by your tradition. Ye hypocrites, well did Isaiah prophesy of you, saying, This people draweth nigh unto Me with their mouth, and honoureth Me with their lips; but their heart is far from Me. But in vain they do worship Me, teaching for doctrines the commandments of men." Yeshua · Matthew 15:6-9
