George Haydock's Catholic Commentary
Psalms 101:28
Fail. This regards Christ, (Hebrews i.) who has established his Church, (Calmet) to be perpetual (Worthington) in this world, (Haydock) and triumphant in eternity, ver. 29. (Calmet) --- The psalm must therefore be understood literally of Him; unless it may have two senses, which those to whom St. Paul wrote must have known, otherwise it would not prove Christ's divinity. The Socinians are greatly puzzled how to evade this argument. (Berthier)
