Granted it is a perfect, but the translators knew that as well. Clearly context had some imput in how they decided to translate that perfect (as it often does)
Place these terms in sequence and indicate whether the sequence is logical temporal or both. justification, regeneration and faith. If temporal give some indication of the amount of time that may intervene.
First faith and then all the others (regeneration, justification, adoption, etc) happen immediately at the moment you believe.
The point is that faith must precede salvation, since it is by faith that we are regenerated,(born again) we are not regenerated to have faith.
