If it exists on earth, it is.
the institution makes ungodly decrees (forbidding men to marry)
Nobody is "forbidden to marry" because nobody is compelled to enter the priesthood or religious life. Seminarians and others in the discernment process have plenty of chances to say "I can't hack celibacy, sorry".
The same person who wrote 1 Tm 4 also wrote: 8 But I say to the unmarried and to widows that it is good for them if they remain [so] even as I. ... 32 One who is unmarried is concerned about the things of the Lord, how he may please the Lord; 33 but one who is married is concerned about the things of the world, how he may please his wife, 34 and his interests are divided. The woman who is unmarried, and the virgin, is concerned about the things of the Lord, that she may be holy both in body and spirit; but one who is married is concerned about the things of the world, how she may please her husband. 35 This I say for your own benefit; not to put a restraint upon you, but [r]to promote what is appropriate and to secure undistracted devotion to the Lord. 1 Cor 7:8, 32-35 [NASB]
How come celibacy is "ungodly" in 1 Tm 4 and highly praised in 1 Cor 7 ?
(Here's the answer. Paul wasn't talking about clerical celibacy in 1 Tm 4. He was condemning certain gnostic groups which did indeed forbid all of their followers from marriage.)
