Those that are familiar with me know I am very staunchly against EP. It is definitely not because I am against Psalm singing. I love the Psalms and hold them in highest regard. They should be frequently sung in worship.
That being said, among the many issues I have with EP, there are 2 that preeminently stick out in my mind (all emphasis mine):
Therefore I testify to you this day that I am innocent of the blood of all, for I did not shrink from declaring to you . Pay careful attention to yourselves and to all the flock, in which the Holy Spirit has made you overseers, to care for the church of God, which he obtained with his own blood. [Acts 20:26-28 ESV]
But let all who take refuge in you rejoice; let them ever for joy, and spread your protection over them, that those who may exult in you. [Psalm 5:11 ESV]
Sing to him, sing praises to him; tell of his wondrous works! [Psalm 105:2 ESV]
I keep harping on this to hopefully dissuade any brethren that are practicing or considering EP from doing so and maybe, just maybe, bringing to light arguments EP church leadership may not have considered.
I do not consider EP as heresy, but it is a significant error, therefore I feel a sense of responsibility to speak out against it. I know I may seem obsessive or harsh in terms of my approach, but I genuinely care that the Bride is given the opportunity to practice Her right to fully sing praises to, and in the revealed name of, Jesus.
How can we have pure worship without including of the Lord's revealed Word as a source in every element?
The words of the LORD are pure words, like silver refined in a furnace on the ground, purified seven times. [Psalm 12:6 ESV]
And it is my prayer that your love may abound more and more, with knowledge and all discernment, so that you may approve what is excellent, and so be pure and blameless for the day of Christ, filled with the fruit of righteousness that comes through Jesus Christ, to the glory and praise of God. [Philippians 1:9-11 ESV]
I abjectly apologize for the times I have been uncharitable and promise to do a better job of tempering my responses.
