Many Christians would accept someone who came into their church based on the following
They dressed smartly,
They spoke well
They were well educated
They tithed their money
They read the Bible avidly
They invited people from the church into their home
They did not get drunk
They did not swear
They did not have affairs
They did not smoke
They did good deeds for everyone to see
They attended all their church meetings
The Pharisees would have passed all those tests with flying colours(I am sure if smoking had of been invented then they would not have smoked)
But Jesus said
Unless your goodness is greater than that of the Pharisees and Saducees you will not get into the kingdom of Heaven
You are so way off base because what you are addressing has nothing to do with practical righteousness as you have stated. What you have outlined above, is that if one practiced these disciplines in their life that grace had nothing to do with it and they should not be accepted. I would receive any of these, in the grace of God, that you have described above but not in terms of their own goodness. You have such a low esteem of believers and have little understanding how to build them up. The very grace you claim to have discredits those that have been saved by it. You project the law upon everyone unless they understand grace the way you do. I have tested it with you many times and you do not even know the kind of fruit that God bares in a Spirit-filled church among the believers that walk by faith in the light of God's word and have their heart established in grace.
BTW - Your quote of (Mt 5:20) should be ...
That except your righteousness shall exceed the righteousness of the scribes and Pharisees, ye shall in no case enter into the kingdom of heaven.
This righteousness that 'exceeds' comes a whole different nature and origin than that of the scribes and Pharisees. Their righteousness was not just based upon the law and their adherence to it but upon their inward nature that they they believed to be without sin. They believed themselves to be a favoured class and stock of that came from Abraham. They had elevated themselves to a status of being sinless inwardly and outwardly. This is why Jesus addressed them as He did in (Mt 23 )...
25 Woe unto you, scribes and Pharisees, hypocrites! for ye make clean the outside of the cup and of the platter,
but within they are full of extortion and excess.
26 Thou blind Pharisee,
cleanse first that which is within the cup and platter, that the outside of them may be clean also.
27 Woe unto you, scribes and Pharisees, hypocrites! for ye are like unto whited sepulchres, which indeed appear beautiful outward,
but are within full of dead men's bones, and of all uncleanness.
28 Even so ye also outwardly appear righteous unto men,
but within ye are full of hypocrisy and iniquity.
29 Woe unto you, scribes and Pharisees, hypocrites! because ye build the tombs of the prophets, and garnish the sepulchres of the righteous,
30 And say, If we had been in the days of our fathers, we would not have been partakers with them in the blood of the prophets.
31 Wherefore ye be witnesses unto yourselves, that ye are the children of them which killed the prophets.
32 Fill ye up then the measure of your fathers.
33 Ye serpents, ye generation of vipers, how can ye escape the damnation of hell?
They couldn't have this man that was a friend of publicans and sinners (Mt 9:11, Lk 15:1), who they accused of being a winebibbler and gluttoness (Mt 11:19), who kept company with harlots (Lk 7:39) and who blasphemed by making Himself equal with God (Mt 26:63-65), as one who they could call the MESSIAH and KING to reign and rule over them. You have to get out of the habit of always classifying Christians as Pharisees because of your experience and own understanding.
There are many believers and local assemblies all over the world that are not predisposed and conditioned to these tendencies that you fault so many Christians with. Perhaps in your own efforts you are guilty of the same thing that you accuse so many others of. As believers God has given us a new nature through the new birth that is created in God's righteousness and true holiness (Eph 4:24). That is the righteousness that we have received by faith that exceeds all other kinds of righteousness.
