The Bereans constantly searched the Scriptures to determine if teachings they were hearing were true or not. John tells us to test the spirits to see if they are from God. Christians have been given the Spirit to teach them all things to guide them in all things.
6. Denial of venial sin.
There are no "little" sins. All sin separates us from God and all have sinned and fall short of the glory of God.
17. Vows of celibacy are wrong and should be abolished.
While the RCC can require what they want of their priests, there is no NT support mandating this.
20. The keys of the kingdom were not just given to Peter.
Were not all of the disciples given the same authority?
21. Private judgment of every individual to determine matters of faith.
See the comment on the Bereans and John.
24. God has not instituted the vocation of monk
God does not call the believer to shut themselves away from the world. We are told not to be in the world or love this world. We are to be witnesses unto all the nations.
25. Feast days should be abolished.
While you can call a feast day is should not be mandatory. 16Therefore no one is to act as your judge in regard to food or drink or in respect to a festival or a new moon or a Sabbath day— Colossians 2:16 NASB
26. Fasts should be strictly optional.
Christians are encouraged to fast...but there are no requirements of fasting on certain days.
And it doesn't even sound like the Roman Catholic is giving up a whole lot when they are required to fast:
For members of the Latin Catholic Church, the norms on fasting are obligatory from age 18 until age 59. When fasting, a person is permitted to eat one full meal, as well as two smaller meals that together are not equal to a full meal. The norms concerning abstinence from meat are binding upon members of the Latin Catholic Church from age 14 onwards.http://www.usccb.org/prayer-and-worship/liturgical-year/lent/catholic-information-on-lenten-fast-and-abstinence.cfm
If you're going to fast....fast!
27. Canonization of saints is thoroughly corrupt and should stop.
There is no NT support for this.
48. Jesus allowed divorce when one partner committed adultery.
Divorce was allowed for unfaithfulness (Matt 5:32; 19:9)
42. Penitential works are worthless.
This "punishment" for sins does nothing to forgive the sins...they've already been forgiven via the Cross.
It’s like... does he even read his own links?
I mean, half of the stuff he rages endlessly at Dr. Luther for are things he himself does every single day here on FR.
