The only Church to be found worthy in the eyes of Christ was: The Church at Philadelphia...

The Key of David (Revelation 3:7-13)
The church that kept the faith

The letter to the church in Philadelphia begins with Christ identifying himself as “holy and true” (3:7). The Holy One is a common Old Testament title for God (Isaiah 40:25; 43:15). He is also true in the sense that he is faithful and trustworthy. God can always be counted on to keep his promises (Titus 1:2)

"The only Church to be found worthy in the eyes of Christ was: The Church at Philadelphia..."

Not true. The letter to the Church at Smyrna had nothing bad to say either. Smyrna, the persecuted Church, was quite worthy in the eyes of Christ. Rev. 2:8-11

[American Constitutionalist]

The only " Holy " and " True " are those who have placed their trust in no other than Jesus Christ Yeshua our savoir.
Christ is the " Object " of our faith.... no other.

Christ is OUR justification, OUR holiness, OUR righteousness.
Any other so called " Righteousness " God rejects... any other " Holiness ( if it is not in Christ ? it's not holy ) " then God rejects.

Acts 13:39:

39 And by him all that believe are justified from all things, from which ye could not be justified by the law of Moses.

That Church kept it's first love.. Christ... that Church stayed faithful and true because they put their trust in no other than Christ alone.
